H pipe
Well regardless of the scavenging, if nothing else you will still be equalizing the pressure from the pulses coming out of each bank, so as said before it might help a little. I really can't tell you how much though because i have never seen numbers from any LT1s with duals on stock manifolds. It could be not even 5 hp or ft-lbs of torque, or it could be more. Maybe somebody else might have a little better idea. I would definitely recommend a set of headers as soon as possible though. LTs if possible (don't know if you can put them in that car with an LT1.) And yeah the X or H pipe is really personal preference, I'm just partial to the x-pipes because they cause less turbulence within the exhaust and, as said by others give a little more hp up top.
