Any one using 351 windsor heads on your 302HO engine? I have access to a set cheap and I was wondering if I should swap out the stock E7 heads. Any issues making the swap?
What year are the heads? This is going to matter alot because they might be large 69cc chambers which dont have much potential and you would be better off with the e7s. If you have your heads off just clean up the bowls on the e7s a bit and they will outflow those windsor heads easy.
i have 351 heads! they are the do0e casting and seem to work great. it takes alot of work to make them work on your 302. its not worth it if you plan on having a machine shop work them. you also need different rockers and pushrods for these. Make sure they have a hardened exhaust seat also or they wont last long on unleaded gas.
