The MP guide lines suggested this.
The OP’s combo is out of wack a bit. The head is ported but to what extent? I do t think he knows what it will flow. I’ll just go on a guess and think out loud here a second and hope not to assume to badly that the heads are possibly just bowl ported and maybe… just maybe, port matched with pushrod protrusion whittled back a bit.
