That only works if you also get TT internals, which utilize lower compression pistons.
You don't really have a choice if you want to go 2mm, as HKS discontinued their 2mm headgaskets a few months ago, which pretty much leaves Greddy... but they are backordered
Have you considered a 3mm headgasket (Toyo, PHR)?? I think it runs $450, and will lower compression to 8.7:1, I believe.

I think that the HKS has a little extra foreskin on both sides of its gasket that provide a "tighter :roll:" seal?
I'd buy the GReddy one. also how low is too low a compression on the IS300 motor? I am running 8:1 on my VW Motor. what would be a good compression ratio for, lets say 20psi on a 2JZ? :wink:
BTW... I think SRT sells the head gasket upgrade for $500 on their website :lol:
