I currently have a 347 stroker with GT-40x heads and am looking to open the heads up for some more flow and power. I was wondering if anyone could estimate what my compression would be if I went with a 58cc head if right now with 64cc heads I am around 10:1 compression. I am hoping to get around 11:1 as that is what I hear is the most compression one could run with 93 octane gas! thanks for the suggestions
