    These heads should really wake this engine up. Tony Mamo always said it's not the quantity of air you put in the engine, it the quality of air that counts.

    I looked at your pic's czizza, and use the same FP 1205/6 gasket on my old Iron heads, they are very thin at the common wall, so I used the old "center punch" trick along with 3M super weather strip adhesive, the yellow one around the ports, let it set up, place the intake and snug down without over tightening, never had the issue since, been a few dozen times. There's more meat on your AFR's, I would use the 3M glue only.
