Pulling the heads

[LordMustangGT]

so I'm pretty sure I blew the head gasket after a 125 shot. It goes threw water like crazy the last couple months, just haven't had time to dig into it. Tonight I'm pulling the heads and see whats missing. 170,000 miles on it. Guess its time anyways. I just order the new Fel-Pro preformance head gaskets. Heard alot of good things from them and there cheaper than some others. I've heard they're really good on aluminum heads for sealing, not that i have any, yet. I'll post some pics of the tear down later.

With iron heads you use the Felpro 1011-1, with aluminium the 1011-2. -Two different gaskets and two different prices. Good luck with your rebuild.

 

[LordMustangGT]

ya, I had to find the part number for them too! 1011-1. Here is how she sits now.

Good luck man...

Head gaskets suck... try and figure out why u blew em so you don't have to do it again, unless your upgrading Also may i suggest some ARP head studs since your juicing or at the very least ARP head bolts.

stop using that POS Fram filter !! LOL

Motorcraft is cheap and little better !

I will be useing a higher performance gasket, but it blew from the 125 shot to a stock 170,000 mile motor, **** happens. It'll have some boost next season. I want low 11's.

lol ya fram is on there cuz I got tired of using the K&N ones. It burned oil so I started putting normal oil with that.

 

[LordMustangGT]

got it all back together last weekend, I would of used ARP stud, but the 95 cobra booster is to big to get around, so ARP bolts did the trick. Runs strong again. I haven't put the NOS to it yet, but it shouldn't blow now. Going to buy a supercharger or turbo for next season aswell. Just want those 11's.

When you say higher performance gasket, what exactly do you mean?
if you have a gasket that seals better with alum. and you have iron heads, the gasket is more likely to wiggle around and cut itself up, esp. if you are running 125 shot. Multi piece metal gaskets are good for high cylinder pressures, and thinner head gaskets raise compression, gaining performance, so...

The Ford Racing graphite or SCE gaskets would work good for this application. Cometics work great but you need to make sure or the surface finish on the heads and block. If the surface isn't what Cometic wants to see you can have oil leaks. The graphite gaskets work great for most people and seal good. I have seen a few Felpro gaskets fail. Felpro has made some changes in their product line that hasn't been good. We stopped using Felpro intake manifold gaskets because the fail all the time now.

When did they start changing things around? I put in some felpro headgaskets right around a year and a half ago.. btw, I know what you mean about the 1250's I've gone through a few of them, damn coolant passage area breaks.

 

[LordMustangGT]

ok the gaskets blew, I thihnk the heads are warped.

 

[TheRedBlur]

buy a new longblock, and pay attention to what type of gaskets you use.

So you didnt have the heads surfaced when you did the gaskets? Doing head gaskets is fairly labor intensive, I am always surprised to find people take shortcuts when doing them.

 

[94gsl5.0]

hmmm... I thought it was pretty hard to warp the cast stuff... did the car overheat? What were you doing when it blew for the second time? Spraying?

Did you make sure to heat cycle the bolts then retorque?

 

[LordMustangGT]

yes yes and yes. Everything was done but I didn't have the the heads checked. No time at the time. I wasn't even spraying, and I haven't yet sence i put it together. I was just cruising down the freeway when I started to noticed it sounded like a miss, and some power loss. I got the time. only took me like a hour to get it apart. I got all the time.
