I have stock heads with a supposedly 0.015 in mill and I am running 0.028 Cometic head gaskets with a 226/238 .635/.630 114 Cam Motion cam.

What do you think your compression is at now? I calculate mine at about 12.95:1, I wish I was at 14 or 15:1, I run E85 100% of the time. I really haven't even tried to run 93 and see if it runs without knock.

My compression is 14.5:1. I’ve got .180 flycuts. But I’ve ran 13:1 setups on 93 without any knock. Just depends on the tuner and how well they can tune.
