Does anyone have the part numbers for the following for a 2002 4.3L:

Comp camshaft
Pro magnum roller rockers
Any performance head better than what I got stock

Does anyone know how much it costs to get ported heads?

Also, what are the typical gains of adding a camshaft or roller rockers?

You need to decide on a cam before you can have a part number. I have never seen any aftermarket heads for the 4.3. That don't mean they aren't out there. Roller rockers are probably good for 5-10 hp. A cam depends on how high the lift/duration, among about a zillion other things. BTW, 304 RWHP is almost 400 at the flywheel. Good luck on that with the 4.3. :bigthumb:
