So I bought a smallport motor with a refreshed head and 30 thou shaved off it, along with a TRD 0.5mm gasket and stock bottom end. keep thinking in my head this thing will ping off its face unless its on E85 or something... whats everyones thoughts and does anyone know the rough compression ratio.

Will be a pretty fun motor that will love bigger cams and some port work.
