Im wanting to get a set of heads rebuilt for the 69 Mustang. Its a stock 2bbl 302 with a offy 4bbl intake and a 600cfm E-brock carb. I want to find a spare set of head to have reworked. What is a good set I should look for?

The early 351 windsor heads would be a good choice(69-74).You will get bigger valves and compression will be pretty much the same.

With the 351W heads, won't you need longer push rods? The Boss 302's maybe? Could be wrong but its what I recall from a friend of mine adding these heads to his 289 some years ago.

Im looking for something in a 302 head. Will all years bolt up? Is the technology the same on all of them?

bttt

I still need info. Are any of the 302 heads better than others. Are heads from a 1985, better than ones for 1977?

If the engine in your 69' mustang is the original one, it has stud mounted rocker arms. Small blocks started using fulcrum type rockers starting around 1977. These heads will not directly interchange. You'll need to change pushrods and use the rockers etc. from the newer heads.

I'd have a set of 289 or early 302 heads rebuilt with 351W valves. (if you want to stick with stockers) Installing oversize valves will take care of any previous seat recession, because new seats will be ground, and they will be outside the radius of the old ones.... which will be high up on new metal.

I would NOT have hardened seat inserts installed. Read the other link I posted in another thread. They are not needed in 99% of applications... and bring risks.

Good Luck!
