AFR 205's milled 0.030 to a 61cc chamber. I gained 43rwhp & 33rwtq with AFR 205's.
Partial throttle response and low end torque are amazingly great. This is a great street combo. Car is at 423rwhp & 403rwtq. I was 380/370 TR224 only.

63 CC heads would equal 11.18 Scr and 8.76 DCR
Normal ranges are 8.4-8.5 on 91 octane gas, and 8.7-8.8 on 93.
My choice would be 63cc to be on the safe side.
Again these are using my specific TR224 112 cam card numbers. Your results my differ.
