Vortec Vs. TBI Heads

Howdy,

I just got a 383 short block, 9.5:1 compression and an Elgin E-923-P camshaft that is going into a 1972 Chevy 4X4, 4.10's and a 700R4. I have a set of 1995 TBI swirl port heads. The redline is going to be about 4500.

My question is: Should I use my TBI heads or get vortec heads? How much horsepower, if any, would I gain by using vortec heads? What would be the best carbureted intake manifold?

Thanks

P.S. Should I use shorty headers or 2.5 inch Chevy ram horns?
