procomp speedmaster heads revisited

Whoops sorry, yes these are 65cc. I transposed numbers. I will fix original post to reflect this. I plan on using an eddy performer rpm 7176 (non airgap) heads dont have heat riser, so i may fill crossover in the intake with fiberglass insulation , and put a valley baffle in the block to help w heat dpak issues. Was going to aldo make a 1/4" phenolic or plywood spacer for under the carb.
