If you use a F-body wiring harness, then any injector that will fit a LS1 will work. Just use the LS1/LS6 fuel rail if you plan on using a LS6 intake. The truck 5.3 heads are not bad and they keep the compression up. Of course they would be better ported or at least milled a little.

Depends on your goals. The 5.3 truck heads already have small combustion chambers, so easy on the milling. To go from stock 61cc to 59cc chambers for example, you would need to mill about .012". The more you mill, the more you need to worry about piston to valve clearance. With a most cam, you should not have a problem.
