Vitaminsea, I'm partial to the roots or whipple. Instant boost, right now! I run pretty much the same set up as yours with a B&M 420 blower. I do have Manley rods and a Kellog crank. My compression is 9.3 to 1 with JE flat tops. I run 9 pounds boost, 34 degrees advance lock in. I always run Av-gas. I'd make sure your fuel supply and ignition is up to the task. I run 1/2" lines to a Holley black pump and two 750 DP Holleys. Ignition is all MSD Distributor, box, coil, rev limiter, wires. You might have to back down the boost and timing a little if you're closer to 10-1 CR. Go with good Fel-pro head gaskets and studs. Aluminum heads will supposedly let you get away with a little more compression since they disapate the heat faster. You might check if anyone makes some heads with chambers that are bigger then your iron heads to get the CR down a little if you want aluminum heads anyway.
Maybe we'll see ya' in Havasu this Spring. Hurry up weather!
