flow numbers go as follows in 28" of h20
289-302 heads 1.78 intake valve 1.48 exhaust intake .100-49.9 .200-91.2 .300-132.5 .400-154.5 .500-168 exhaust .100-41 .200-71.6 .300-95.1 .400-110.7 .500-120.1 .600-124.8 e7ta-aa same valve size intake .100-55.4 .200-101.3 .300-140.9 .400-150.8 .500-164.6 exhaust .100-42 .200-78.9 .300-102.4 .400-110.8 .500-114.2 They can flow much better with a mild home port. Hope this helps. Also since your compression will be raised you'll be adding about 10 hp from the point gained. Add that to the porting another 10-15 and you've got some nice numbers there.
