Most Pontiac heads seem to exhibit better intake flow than exhaust flow. So you'll want to make sure the exhaust system is properly set up for the performance level you are trying to achieve. That means a good set of headers, an x pipe crossover (Bassani makes a good one) and at least 2 1/2 inch tubing all the way back. Remember that torque is what really makes the vehicle accelerate, so have the heads properly done, get a hydraulic roller (I'd like to see it no bigger than 230/240) and a set of the Comp Cams beehive springs and you'll have a good balance of performance and driveability. You have not mentioned the tranny. If it is a TH400, you're going to want at least 3.42's and a decent converter in there as well. If it is a 4 speed, we need a whole other discussion of how it ought to be geared based on which gear box you want to run. I'd also like to see an MSD 6AL and then we need to get Crane Cams to make a Pontiac version of their electronic distributor. You set the timing curve with dip switches on the distributor and it has a MAP sensor rather than an advance canister.
