Hallo,

i often read that ppl with high #'s use cometic head gaskets instead of the stock honda gaskets... can anyone tell me why the cometic gaskets are better then the stock gaskets?

if you have a stock bore... I'd just stick with a oem honda headgasket... there's alot of guys makin 400-550hp on oem headgaskets

so the main difference is the bore size? or is the cometic gaskets are also stronger?

Thanks

cometic gaskets are made thicker separating the head from the block a bit-- some up to 3mm therefore lowering compression and stress on the bottom end

this also is safer for detonation.

Of course there stronger why dont you compare materials...

Some Cometic come with the hp rings too and help preload when you put on the head. Just better for higher boost levels I believe. I have gone with 3 of them on several setups. Never blew one and run high boost too. should be safe with a stock headgasket up to like 20psi. I have seen higher

i was told that it is best to use these if you have a large bore such as 85 or anything much higher than stock cuz alot of other hg's are made from the oem gaskets just bored out...
