I had a set of Gessler ported Edelbrock heads on my 464. Full weight 70 Skylark ran a best of 10.96@125. 11 to 1 compression, Scott Brown cam similar to a 308s, ported SP1 intake and 950 carb, 3.73 gears. Now the whole top end is on my son's 85 Regal with a 464. He has about 10 to 1 compression and T/A 413 cam and 3.42 gears. So far, with no real tuning he has ran 11.47@120. Both engines shifting at 5500 rpms. The heads were not fully race ported. I went to Stage 2 heads on my car otherwise I would still be using them. Ken
