The casting # 15 heads with there stock 1.96" Intake valve peak in Intake flow at 185 cfm, the Exh side even though it only has a 1.66" Exh valve flows 155 to 158 cfm.
The overall flow ratio is in the low 82 to 84 percent range which can mean that even if your pumping out the Exh thru stock log Manifolds you do not need a duel pattern Cam like your running.
At the Intake valve lift of the Crower Cam your getting about 175 cfm, this amount of flow will be enough to make a very optimistic 358 hp at the flywheel.
