Which SBF cylinder heads?

streetstang67 · Apr 25, 2005

I'm looking for more power; I was starting with a cam and getting stuff to match it, but heads are more expensive and need to match as well, so I'm goin to choose them first. This car is a weekend car for the street. I dont know how much gas mileage I can expect, but I dont really want to change the stall or the carb. I dont really want to change the intake either, but people say the performer RPM is way better. So what heads do you suggest? I'll post a poll with the most popular heads listed, but please reply and tell me why you chose what you did. Thanks!

For your application, I think the RPMs will be great. They make very good power, are cheaper than the very popular AFRs, and have bolt holes that are steel lined and in the stock location.

Don't forget that money is an issue...

I voted for the AFR's cause their performance can't be beat. If money is an issue though te edelbrock performers are pretty good too.

i voted for the windsor jr's, they would be a better choice for what you're planning if you can't afford the afr 165's all the other heads you ahve posted have too big of a combustion chamber for your 289 and you'll lose a lot of compression, possibly enough even that will be disappointed with them. with those heads i would use a comp extreme energy cam, i can't get onto their site right now, but look for something with 220 degrees duration @.050, with the extreme energycam that should get you around .485-.495 lift at the valve. keep in mind that with any of the heads you have listed you'll have to change most of the valvetrain prices as well, pushrods and all of these heads use the newer style pedestal mount rocker arms or stud mounted rockers, so you'll have to change the rocker arms, and fulcrums as well, so that's another added expense, if you go with stock replacement rockers the cost will be small and you might be able some good used ones from a local machine shop for next to nothing, though.

well i was finally able to get onto comps site, looks like the XE256H-10 would be a good choice. it has .477/.484 lift and 212/218 duration at .050. would be a good match for either the windsor jr's or afr 165's in a mild street car. this won't be a barn screaming combo but will be substantially hotter than a stock 289 and still very streetable with a god idle and decent MPG as well. maybe even better than the stock 289 if you can keep your foot out of it. i would also recommend either a set of tri-y or shorty headers with this combo and it should work well with your stock convertor also.

lovin my 40-p heads, you can pull them off explorers, and if you dont go with a radical cam over .500 lift then they will probably end up the cheapest, however you will need to get some headers to match, and you can modify a cheap set of tri-ys to work, i did and they work beautifully

I don't think ANYONE can go wrong with AFRs. Period.

streetstang67 · Apr 25, 2005

Well I checked the combustion chambers and it looks like the roush 200s have 64cc which is too much compared to my 58cc (?) current stock heads. Also, the GT-40 P heads probably won't work with my hooker headers, right?

i have the edelbrock rpm's but if i had the money i would have gone to the AFR's. also rember the AFR's may need some other work done to them to match them to your intake.

like someone else said ...AFR's can't be beat in performance.

edelbrock rpm's are a great buy also!

Red66GT · Apr 26, 2005

I voted for the Edelbrock Performer RPM's. Got a pair myself and they really make some great power w/ a mild cam and long tube headers. I'm still running the regular performer intake and a 600cfm holley carb.

As far as price goes, you can get a pair for about 300 dollars cheaper than the AFR's from Summit, so they're a good value.

streetstang67 · Apr 26, 2005

Not much has been said about the windsor Jr.s...are they any good? So far, #1 is the most expensive out of the bunch (AFR), #2 is the 2nd most expensive, etc...

brianj5600 · Apr 26, 2005

I have 185 AFR's, which are not a ton better than TFTW's. I voted TFTW because that is what I would put on a smaller 289. They can be had for about $300 less than AFR's and are a little better than 165's.

streetstang67 · Apr 26, 2005

How crazy could a machine shop go porting my stock heads? is there room for noticable improvement?

84convertablegt · Apr 26, 2005

i only wish the roush 200's came with 58 cc chambers. they are the best deal imo even though they are iron heads. they flow great and are fully assembled and ready to go for way less than afr prices. u could have them machined for 58cc chambers, but then where would u be with cost. decisions decisions. im in the same boat, although i plan on waiting a while before i do new heads.

jst6 · Apr 26, 2005

if you like AFR why not the 185's? the 165's seem to be too small for the money. if your considering those the edelbrock RPMs are cheaper for the flow.

my two pennies

i found afr's for like $1200 and the rpm's were like $1800

FWIW, I have a performer, 600 holley, stock cam with 1.7's and the afr 165's..no complaints.. with a stock converter and an auto, you're going to need more bottom end TQ, or the car will suck off the line..

So your running 13.58@102 with that ? That is basically my engine with AFR165s, right?

84convertablegt · Apr 26, 2005

thats an 84 vert though, i had one, hence my username, they are 2 different animals in stock form, trust me. the 84 vert did much better running down the strip than the 65 does

coolblue65 · Apr 26, 2005

IMO the best heads for your money are the Trick Flows, you could get the heads and the Edelbrock RPM intake for the same price as the AFR's. Also, from the various articles I have seen TF's flow better the AFR 165s. Also, I believe the Edelbrock RPM heads have the 2" valves that will not work with stock pistons.
