Message: [QUOTE="6speedsd, post: 1512694, member: 1242"] Since that deal fell through, I’m considering a head upgrade for the 302 for the time being. Whenever I do upgrade to the 351w, the heads are interchangeable, so I’m not out anything really. I’ve been looking at the different options for a while now. Seems the general consensus is a set of AFR 165’s is the “best” choice, but there are a ton of options in the $1200-1300 range. TFS, Ford X, Edelbrock.....all seem to have comparable feature, but is there a significant difference in a $1700 set of heads over a $1300 set? Also, cc’s..I’m under the impression stock E7 heads are around 64cc and something like 8.8:1 CR. Running a 58cc would give me a higher CR, but what would be more ideal given my goal....58, 60, or a 62? I don’t want to raise it so much that I have to start running 93 octane. Am I flirting with PV clearance issues if I drop to the 58? It’s a 92 block, so it has the factory forged pistons with 4 valve relief cuts (I’m pretty sure it was 4 and not 2). Sticking with either the 260H, or maybe slightly larger...500ish lift max I’d say. I read an article where they tested several heads in that price range, and the TFS gained more flow and better numbers than the Ford X head, and Edelbrock was below the Ford. I mean if the AFR’s REALLY ARE more superior to any other I’ve listed, then it’d be worth saving a while longer and getting those. Sent from my iPad using Tapatalk [/QUOTE]
