Hey B...my 'tiny' heads flowed 390 CFM @ .0600, so we went with 23x/24x 630 lift. We're looking for early powerband tourque, not so much top end. I think you need a much bigger cam? Was Shawn able to get more timing in it and how much? I bet you have alot more 'sillyness' letft in that motor before tuning is done...
