Need advice on headers and exhaust setup

[RedHeartbeat]

I have one more question too, I bought a set of precision 42lb injectors off of a guy from ls1tech.com, but they are a lot taller then the stock 6.0 truck injectors, the only way I can see making them fit would be to put spacers on where the rail bolts into the intake manifold, is that normal? I will take a picture of the injectors when I get back from lunch.

Very common. They must be fbody LS1 injectors.
