[X-TECH MAN]

Since your not limited to rules you should try the Edelbrock Alum. Magnum heads when $$$$ is avaliable. They already have 2.02 intake valves, lighter weight, use chevy valves and rocker parts and flow pretty good out of the box. Just be sure to check the C.C.s. They are not even close out of the box in that dept. In the long run they are cheaper than modifying the iron heads. We had to use a larger drive shaft also (3720+ lbs). Used the larger joints and a 3 1/2 shaft. Never lost another one. Again Im not that up on turbo engines but Ive heard they are camed differently than a blower engine but boost is boost. It just comes in at a different RPM range. Food for thought until someone who really knows could help you out. Terry
