aftermarket 2v heads, never.

darkside03gt · Oct 14, 2008

I have called all three major cylinder head manufacturers with no results. neither edelbrock, trick flow or patriot are even working on a set of 2v heads for us 2v guys.

The reason i started asking around is because patriot just came out with a new 3v head for 05+ cars that supposedly flows better then ported stock 3v heads.

according to all three companys i called not a single one even has a 2v head on the drawing board. edelbrock wont touch any ohc cylinder head because they are too precise and expensive to manufacture. trickflow is busy with alot of mopar stuff for the next year or so and patriot had a 2v head on the drawing board at one time that swapped the intake and exaust valves around in order to get better flow but abandond the project for reasons not given to me.

So I gues the 2v guys are stuck with ported factory heads. not that we can make big power with them but it would be nice to not be backed into a corner when it comes to building a new engine.

anyone heard anything different? this sucks.

its been that way for many, many years.

I agree man - i like my ported heads for sure; but i kind of feel like they should have started with heads that need the flow the most (i.e. 2V guys) instead of 3V heads which already flow nicely. Also we have 8 years of cars that use 2V heads - you'd think that would trump the 4 years so far of S-197's.

I think it has to do with 2 things.
1. 05+ stangs can be tuned very well and most likely would pick up a lot from an aftermarket head/cam set-up.
2. 96-04 guys can put B, C, or tumbler port 4V heads on our cars; so they might think there's less of a market.

I aslo dont think that these companies see that 1800 isnt a unreasonable price to pay for a good cylinder head especially when you look at what mph or fox lake ported heads cost.

I thought patriot made 2v heads

nightmare, those are ported stock heads

The only thing close to aftermarket heads are Livernois' new heads that have a revised combustion chamber design. It actually decreases the volume of the CC. They have already tested them, but I haven't seen them on their website. But when you see the pricetag is going to be at least 3k for a pair

Stangdriver13 · Oct 14, 2008

I would guess that they are not attempting to make them because the gain would not be significant enough for people to purchase the heads. Also, it would take a lot of time and money to design and test the heads. I don't know about you guys but i refuse to spend to $1500 or more for a 20 to 30 hp increase. Just save for FI at that cost. This is the most likely reason that Patriot threw it out.

2v's are the bastard child, thats why.

Everyone knows the best route 2v wise is forced induction.

You can run 400rwhp reliably on a stock bottom end that is in good shape, with a great tune and some common sense.

Try getting 400rwhp from a naturally aspirated 2v and see what kind of money you spend... by the time you spend THAT much money (can you say 5.1 stroker, massive headwork, cams, right intake, machine work would be $$$ in that setup) you can swap in a forged bottom end, some blower cams and up the boost well into whatever range you need it to be.

Same goes for a turbo setup or nitrous.

We are screwed for N/A applications as far as reasonable cost goes... we just deal with it. Some of us are happy with a high 12 second all bolt on/tuned/geared GT at full weight... some of us want a mid-low 12 second bolt on/tuned/geared GT with alot of suspension work and some weight reduction...

Some of us want a full weight street car that runs 12.0's or 11.9's with just a blower and supporting mods... so on.

I won't be complaining much about the flow of my 2v heads when i'm forcing 15+ psi through them

Keep in mind though that it's really 6 years of PI heads, 7-8 years of non-PI heads that all are now out of production. On the flip side you have 3v heads that are going on 5 years of being on production cars and is still being made. Now if Ford changed direction I'm guessing all of projects like that would be dumped. OHC heads are a major project with all the machining required and the cost jumps big time. Let's not forget the old FRPP SVO heads for the non pi heads they were made by Ford and never really sold all that well due to price. Any aftermarket company has to look at that and really think if it's even worth it.

I just talked to afr today and they are looking into producing a modular head. they just arent sure what one yet but it sounds like it is between 2v and 3v. they guy i talked to said that they get calls everyday from people asking about 2v heads and it has put a light on the possibility of actaully desiging a new head. He also said that they see a very big market for a 2v head. so there is a dim light at the end of the tunel.

DBMSTNG · Oct 15, 2008

i don't know why someone wouldn't look to make a 3V(or more) head for the 2V motors. yes you'd need new cams, but pretty much everyone gets new cams with ported heads anyway.

BurningRubber · Oct 15, 2008

AFR making a mod head would be great. They put out very well made and proven heads.

I couldnt agree more. either afr or trick flow heads would be great. I hope they are done by the time iam completing my build in about a year or so. I told afr that I would pay $2000 for a set of quality heads that out flowed ported heads. especialy when you compair that price to say fox lake heads that cost $1800.

02nightmaregt · Oct 16, 2008

I would love to have a set of aftermarket heads. I don't think i'd like to spend the money on a head/cam swap if they are just ported pi heads. i'll just get cams and springs.

After oh 12 years of making the 4.6L 2V in the mustang, the aftermarket is finally coming out with heads. A certain company is scheduled to announce their release at SEMA in a few short weeks. The word is that the heads in cast form will flow like that of a 4V head, and with port work will approach the 300cfm point on the intake side. Price is supposed to be in the $1500 range for a set.

We'll be checking it out at SEMA and see if we can get some pics and more info on it, but looks like there is a future after all for the 2V crowd.

You could go with 3v heads ported on a built motor not to hard to do and more N/A hp. There is a video on youtube of some one who has one in his 2000gt built motor and 3v heads at 350hp.

2v's have made that power as well.

While not an expert on this topic, Ill share my opinion.

I wouldn't hold my breath. The PI heads are still are good. The flow well with a port job and upgraded valves.

Personally, it's been proven that these motors due cost money to build if you don't do the labor. For most people, paying for NA work and labor is just not worth it for what you get.

I've been down the road a time or two, and without the expertise to do all of the work myself, I found it was just too expensive the last time around. Even with a set of good flowing 2v aftermarket heads at 1500, you are looking at 3000 dollars with a port job, valves and install, without a tune. Cams, tune, etc, and you are looking at 4000-5000 dollars if you don't do the labor. For what, 300-350rwhp max? For 10 years I have been waiting on aftermarket 2v heads, with lots of speculation, and still nothing.

As Bill mentioned, the ohc is much more expensive in R&D. Production cost is also higher, as there is a lot more material. This site used to go through 2 pages a day on the tech and talk forum, as did other sites. We are lucky to get through 1/2-3/4 a page in talk and less than that in tech nowadays, and it applies to other forums as well. As much as some of us love the 2v, I have a hard time believing the aftermarket is going to continue for a dying breed. For most of the population, a good blower kit like the Mongoose kit makes a lot more sense.

To me these 2vs aren't that bad. I'm doing the N/A thing with a goal of 300+rwhp. When you think of it thats around 360+crank hp. That's 100hp over the stock engine and cheaper then going FI. I will have a completely built car from suspension up to the engine for less then the cost of buying a SC kit.

aftermarket 2v heads, never.
