The HSD intake Skip borrowed from me is nice piece. I have two Holley Street Dominator intakes modified by Dave Bischopp. One uses my HP950 carb, the other has the carb flange modified for a 1050 Dominator carb. Both have port exit openings about 2.300" tall and use a SCE #128103 intake gasket that is about 2.320" tall. After the port work there is about 0.125" material above the ports for gasket seal.
The 'regular' HSD intake with my HP950 carb and a 1/2" open spacer made 589.4 hp at about 5700 rpm on the dyno, this was on a previous pump gas 4.210 stroke 462cid street engine. With the same engine & carb my Victor intake with 1/2" carb spacer made 600.9 hp at 6000 rpm.
As Skip mentioned his "high port" modified Torker II and my HSD intake dyno'd identical on his 550 HP pump gas motor.
