Which Head Gaskets

[scrobbyd]

Yes I would like to know which head gaskets are the best stock replacements I have always used OEM head gaskets because I heard they where the best. But it seems like they are getting harder and harder to find. But what I would like to know is how does the Felpro or something like that compare.

Thanks In Advance

From what ive read and know what's on my car. The Fel-Pro 9441's are the correct ones to get.

Now ive never replaced a HG or anything, but that is the number for HG from them.

Actually in comparison will the felpro hold up as good as the OEM.

Thanks again :wink:

The 9441's will hold up fine. Proper prep for the mating surfaces and a very through thread cleaning of the headbolt holes cannot be overstressed..it will make ALL the difference in the world especially under higher than stock boost levels. HTH

 

[scrobbyd]

Any more opinions.


Thanks again

Do a search for Felpro 1000

 

[SHADOWII]

the 9441's on the 3.8 and the 1000's for the 4.1:biggrin:

Cometic HG's

Been running the first production set of Cometic MLS viton coated HG's for
2-3 years with iron heads prepped for Cometics. They are great, but will not blow out, so the lower end of motor must be strong (steel caps Etc) at high boost.

i have not had the best of luck w/ the 9441's, but i know plenty of people who use them. i am just finishing the same task and thought i would try the victor reinz gasgets, heard good things about them and they look more stout than the 9441's. i have a set of fel-pro 066's that look like they would hold up and also they have a small bead of silicone around some of the passages. again, i chose the v.r.'s. anyone use the 066 fel-pro?

SCE TITAN Head gaskets

I run a new gasket from SCE that has the o-ring built into the gasket rather than having to o-ring the block or heads. I have run 23 lbs of boost with 23 degrees of timing with no problems.

 

[BlackBandit]

I've had the 9441's to 26 psi and 25 degrees of timing without any problem. That was with TTY headbolts and when I took the heads off (wiped cam) the headgaskets looked perfect. HTH james

Not sure about that.

Feldpro 1000 all the way. My 2 cents Brad

Shadow,
I interpreted your post incorrectly.

Sorry to hijack..... what type of prep? Which part number cometics? Have you had any problems with them seeping water or oil?

 

[TURBOELKY]

i've blown a pair of 9441's, now run stock gm head gaskets. But I think any headgasket will blow under certain circumstances. It is all about the prep as stated above. Most people forget to re-torque them after a few heat cycles, and go balls out right out of the garage instead of proper break in. But i'd rather have a head gasket blow before my bottom end. There has to be a fuse somewhere, and the head gaskets are the chosen ones's

Call Full throttle at 586-294-4404, they have the complete kit made by Victor, it has everything except the valley pan for under $100. The heads gaskets are just like the stock style graphite looking. I have used Felpro to cosmetics but these are the best bang for the buck, I believe the kit even has the turbo oil drain gasket. I have used about 10 kits on different motors no problems at all. I think it also comes with a rubber oil pan gasket but I prefer a cork one.

Stock GM ones would be the best I would think...
