Which Head Gasket

[RdRunnr]

Are you power guys running and why did you chose the gasket you are running?

[RadialX]

permatex ultra copper.............its cheap if you buy it for use in a caulk gun...............

[fast5liter331]

Fel-Pro right now. When these blow i'll be switching to Cometic.

Ok, I was just jokin,...............


I ran felpro pt9333 with a stainless wire in the head..............for maintinence reasons we usually changed them after 20 runs, but this last set went 40 passes, with the change over to the X trim we were seeing 29psi in high gear. I pulled the heads when I blew the motor and the gaskets were in perfect condition.

if your building a new motor, I would use the felpro MLS or cometics, the deck surface and head surfaces need to be super smooth for them to work properly. replacing gaskets I would use 9333

Blown head gaskets are from detonation, not boost..........just remember that, if you blow one, its a tuning issue.

WERD.....I have two 8548PT2 FelPro gaskets with 6 burned holes to prove that one...lol...

i run the FRPP B51's i was running the 1011-2's and was having bad luck with them, switched to the B51's and love them

that's how most of my car is held together :lol:

When you switch to the MLS will you still need to change them every so often Spence, or will they last longer?

I have used regular gaskets (9333/ b51's etc..) , cometics, than copper, now back to cometics. Copper just wouldnt seal right and seeped antifreeze, the fel pro's held fine for couple years till i turned up the wick too much and the first set of cometics held through enough rattling (way to lean tune) to eat a piston. This set should be my last set, i finally broke down and got bigger injectors and a pms lol ;)>> The cometics can be reused like copper and do not need to be replaced for a couple seasons at least (i never heard of anyone having to change cause of age)

I run cometic on my set up, have reused them 3 times now with no problems!

I am running the cometics now, and so far they are awesome. They have lasted for several 600+rwhp passes on the dyno and several 9 sec passes on the track (/me knocks on wood).
