couldnt you run a thicker Head Gasket? i know it wont make up 1.5:1 difference, but itll help.
i know the dsm guys have a choice in HG thickness, because the 1g motor has lower compression than the 2g motor, and alot of 2g guys get a thicker gasket to bring their compression down, or the 1g guys will get a thinner one to bring it up.
