daddy cool, i think that guys rolling road must be over reading or somin!
what housing do you have on your turbo, .48, .68 etc?

both the wrc and the cometic head gaskets are virtually the same but the cometic is half the price so i would go for that one.

if you have the cash then by all means go for the 200.

Do not wire ring the block! its not bloody worth it cause if it aint machined perfect or the wire isn’t sat in with no join line then you will have a weak point and pop goes the weasel!
and if you are running that stupid amount of boost which i doubt you ever will then you definatly need the multi layer type gasket not the grp a!

were you running the bd10 and 14 cams when you got this 450bhp figure?
