Keep your > compression ratio at 7.5:1 or lower. I'd recommend _not_ semi-hemi'ing your heads, no matter what. It's one of the worst ideas in the ACVW world... for one, it'll make you MORE likely to detonate, especially under boost. Enlarging the chambers a *little bit* (i.e. w/o removing too much quench) is a good idea. If you still want to drop CR more, opt for some dished pistons.
