My head porter just e-mailed me my flow numbers and here they are:
.100 66/47
.200 138/101
.300 195/143
.400 242/172
.500 266/187
.550 274/191
.600 277/194
They were ported by Lloyd Elliott, I am happy with the numbers. My question is I am getting my car dyno tuned right after I get the heads on, with 7lbs(mods in sig) I made 428rwhp at 5600rpm, wondering what #'s I'll be near with the new heads and would I cut-out be a benefical for power gains. Thanks

 

The heads will help out a lot, just wait and see
