Pete Incaudo, owner of VMax Motorsports, worked on the development side for the LS1X World Warhawk heads, so that made our cylinder head choice a little easier.
also had to angle mill these stock castings to arrive at an optimum 62cc combustion chamber that yielded a 10.5:1- 11:1 compression ratio, which is fine for the street.
The combustion chamber in these heads is fully CNC machined.
On the exhaust side, Pete hand ported and polished the short side radius and intake runner entry to enhance flow through the intake without enlarging the port volume.
On the intake side, the port received minor work on the short side radius and floor with enough material removed to eliminate the casting lines.
was working on the heads and checking for pushrod clearance issues, he
found that there was interference with the casting.
then had to hand grind the pushrod opening and unfortunately, since the casting was too thin in that area, to get enough clearance he
broke through all the intake port walls.
