Its best if you do a compression test before you strip it down.by skimming off 50thou you would probly gain around 30/40psi over at good standard engine..I allways do a compression test on the ma12 engines i send away to be rebuilt for racing and a good one is allways around 140/160psi and when they come back i do a retest there around 210 psi
