I will honestly try to help anyone I can but sometimes you gotta call a horse a horse. When I see a picture of a head like the one on page one of this post I call BS. That is NOT the way you port a space limited head (intake runner CC) like small block mopars are. These 170cc runner heads take material removal and if you look at the "common wall" between the ports the wall bends in way to much. That common wall needs pushed over as far as possible and is why I sleeve the head bolt holes. He states that that head flows 300 but yet the track numbers at his weight don't reflect that at all.
