I recommend using one of these lunati solid roller cams - with the high flow heads you have a hydralic roller just wouldnt serve your purpose.

They both have torque curves like a friggin rainbow, originally devolped as a jet boat cams but since have become real popular grinds for bracket cars because of the huge turque curves also they are real easy on valve train parts.
