www.cometic.com has high preformance headgaskets for 650. Anyone have one?
thanks

 

QUE... I'm really not trying to be a smart a$$, but high performance head gaskets ??? what do they do ??? it is my understanding that you don't need anything like that, unless you are going to a much higher than stock compression ratio ??? perhaps they are the ones that came in my FST kit ??? those were a little thicker than stock, but actually, then, probably added back some of the space that was planed off of my heads during rebuild...IMO, 99.9% of the rebuilt Prairies should not need a high performance head gasket...

 

Im not really sure, I figured they were just a thinner headgasket for more compression. An alternative to getting high comp pistons. I think your right, for really high compression motors.

 

i dont think it will do much, if anything, i would not waste the time and money on it. just my 2 cents.
