Assuming-6.6cc reliefs in the pistons, 4.180’’ gasket bore size & 60cc T.F chambers your SCR should be around 10.6:1. With a 0.039’’ gasket, 10.9:1.
You can bring your SCR down by polishing the CNC tool path marks off the chambers. Added bonus of some pre-ignition resistance. I did this on some Eddy CNC heads and gained just on 5cc’s. Did it by hand, started at 80grit IIRC, went through the grits up to 2000, then polished with a small die grinder and polish wheels. Came up beautifully. A head porter can do all this, of course.
The T.F chambers are smaller than the Eddy’s, but even if you gained 3cc’s with a 0.039’’ gasket you’d be back around 10.55:1 with a better quench / squish. Best of both worlds.
