If they're 5.7l castings, the peak flow is pretty good. The flow at .200" & .300" could be better by 5-6%. They should produce some respectable power though. <img border="0" alt="[judgement]" title="" src="graemlins/gr_judge.gif" />

Your flow numbers are alright. These heads should work good on a street engine. Problably below 6600-6700 rpm.
