Default 6.0 block with l92 heads

Just bought some parts off a guy at a real good deal. I got a 6.0 cast block, a new set of cnc ported l92 cyl heads, a set of diamond pistons bore 4.030, comp height 1.125, rod length 6.125, effective volume -1.8cc, and cam is comp 244, 254 duration at .050, lift is .612, .622. Plan on buying a callies crankshaft, and callies hbeam rods. Is this a good combo and does anyone see any concerns i need to address. This is going in a 02 ta ws6, m6. Thanks for any help.

That cam is on the big side for LS3 heads, especially for a 370 cu in engine. Plus it might cause ptv issues.

For a 408 that's a decent cam, just make sure that the pistons have valve reliefs cut in otherwise you might have PTV issues especially with milled heads.

Just checked the pistons, they do have valve reliefs in them. Does anyone know what kind of hp i should be looking at out of this set up. I just ordered a fast lsxr 102mm intake, what tb do i need to go with.
