As the question states, what headgasket are you guys using for high power? And are you o-ringed?

 

most ppl run stock head gaskets i think even on high power evos

 

Cometic

 

hks hks hks hks hks hks

 

I ran a cometic, 35 psi on a 35R and had no problems. My head and block were not o-ringed.

 

this is funny , i was trying to figure out what head gasket i am gonna use for my build

 

We have the AMS Head Studs,cooper o-ring and stock head gasket did fine to 54 psi

On my old setup we where not o-ringed but ran the AMS Head Studs to 110ft lbs and a stock head gasket

 

If ifarted2 is using the stock one, anyone can. I think for 40psi+ O-ringing the head is a very good idea. ARPs are a must.

 

stock +1 mitsu metal = good stuff

 

I am not a vendor, so I have no interest…. Us anything except COMETIC!!!

 

Use the stock gasket.

 

Explain to me why you would choose to oring the head

 

stock, o-ring, AMS head studs

 

You DO know that running a Cometic gasket requires a certain RA on the block and head right? If you just stuck it on and your machinist didnt have any idea about this the gasket probably failed because he ran normal table speed while decking the surface. High table speeds result in rough finishes and Cometics will not seal. I suggest hand lapping when using Cometic gaskets. Havent had one fail yet.

The the original poster. If you're not trying to set the world on fire, stock will be fine.
