Interesting you post this because I was trying to decide if I should mill the 452s as you did here or go 915s. I could go either way right now as I have both available.

The engine ran plenty good I just had to start pulling out timing as the summer temps got up there.In the end I had 10* out of it but it was 100* plus outside !
