An update:
Jack with Valley did a great job giving my motor a once over and found the distributor to get junk (replaced with MSD), spark plugs gapped way too tight as they appeared to never be checked out of the box and the butterflies for the secondaries on the carb hitting the divider in the air gap intake. The motor liked 34 degrees best with 76 and 80 jets. Made 507 ft lbs and 455 hp. There was a slight oil leak out of the front of the intake so when he has it off he is going to gasket match the ports and it’s going in the car. I am a little short of my 500hp goal with the iron heads but he says with the heads milled a little to increase compression (currently he calculated 9.2:1) and a larger cam he believes 500 hp is doable.
Thank you to everyone for tue insight and suggestions on this build.
