Thread: 69 302 block 75 heads, pushrod problem

Thesals; Listen to GT Dan he's got it right,You have to take into account the kind of cam you are using, lifters, rockers, screw in or press in studs, all these things can make the push rod legnth different. The plate that you are trying to unscrew on that ford head, is cast as part of the head if its what I'm thinking of..a lot of Fords have these and they don't unscrew. Now about IDing the heads look under the intake ports on the bottom of the head, there should be an ID there. Ok in 1969 a 302 had a head chamber size of 56.7cc In 1975 the head chamber size was about 67.5cc The compression in 75 was 8 to 1 and 122HP in the 302's. In 69 the compression was 9.5 to 1 with 220HP in a 302 with a 2V. These heads will fit but if you have changed your pistons you will have to watch your valve to piston clearance and you may have to order a specail head gasget. because the water ports are a little differant. I ran the same set up a few years back and it works great. It's a good way to get extra horse power. Oh and I had the same problem, the push rods were to short and made a taping sound. But I was also running a Sig Erson cam, it was a TQ30 and ran like a raped Ape. That was my favorite car to this day, I would still have it but some one decided they wanted it more and stoled it. hope this helps you
