Fastburn vs. Vortec
I was wondering which heads flow better for a small black? I'm going back and forth between ideas right now, and I like the idea of the fastburn and the vortecs. So which would you guys go with?

Depends on what you're building. For low cost torque with lifts below .5, the vortec is hard to beat and about 1/2 the price of the fast burns. However, for larger displacement with higher lift cams, the fast burn is your head.
BTW, the fastburn will accept both the vortec and "standard" intakes.
From GM's performance parts site, "Intake manifold mating surfaces are drilled and tapped for both Vortec and conventional raised port style manifolds. "D" shaped 78cc exhaust port and runners provide adequate flow for applications well in excess of 500 hp. Raised runner (.240" higher than conventional 23? head) intake ports with 210cc ports and runners provide adequate flow for applications well in excess of 500 hp."
