I'm not sure what I'm going to do about compression ratio right now. If I run a .030 gasket (which is what I want to do, I'm looking for a ~.045 quench) that puts the TFS heads at ~11.8:1. I'm not comfortable with a SCR that high. If I run a thicker head gasket the quench starts to suffer pretty badly.
What I'll probably do is use a .040 gasket on the TFS heads, which puts me at ~11.5:1. I don't like the compression that high, but I don't really see another option.
Then, I'll use a .028 gasket with 65CC chambers on the AFR heads for a final compression ratio of ~10.8:1.
It sounds like you have the piston .015" down the hole. I wouldn't be happy with any more than a .045" quench, at the outside. How about doing some "unshrouding of the valves" in the TF heads to try to get the combustion chambers closer in size. Not only does this help the test, but it might make gathering parts a little easier too. Good luck. I wish I could help with the Visa problem, but I'm afraid I can't.
