Hi Tom
I have an SVT and I was thinking to increase the CR by using the ztec Head Gasket. When I calculated it it was about 0.5 or 0.6 increase in CR. I was wondering is this worth it or should i mill the head and get a 11.0 CR if everything stay the same how much more power you think i can get my guess is around 5 to 7 whp is that right?

Thank you in advance.

First question would be what octane fuel can you get , There is a point where the amout of timing taken out to curb detonation will take any power gained from the higher compression away
