So I had made my mind up on which heads I was goin with, but I was doing more research and I'm not sure again. So let me ask y'all.. Afr 165s w/ 58cc's or tfs tw 170 w/ 61cc's? I've did the research on the flow charts and out of the box the flow like ~2 cfm's different at .500 if I'm not mistaken. The extra compression of the afr's look nice, since I'm in a high compression craze right now, but I've heard that it's tf>afr... Thoughts, ideas, and opinions are all wanted.
