Found my first flow test of the BM's OOTB with no "help". The labelling is backwards and I'm not the best at online charts this early in the morning. J.Rob
decent 'ported factory iron head' numbers, till .400, then its like factory ported numbers again....lol ....
If you don't lift the valve .680-.700 .....these aren't the heads for you....these heads are over priced factory aluminum.
The exhaust port ...now that shows you they're just going for max and no balance...wtf.
New guess, 532 hp
Disappointed.
