Question 390 with 428 heads

Hello, so I have a 1964 Ford Galaxie 500 I bought a couple years ago, I bought a parts car for it for $900, mostly because I wanted the 390 engine. I sent the engine to get redone, as I am more of a body guy, andI put 2 grand into the engine being redone. Now the mechanic says it has 428 heads, and I have been toying with the idea of selling my galaxie, but I have no idea what a 390 with 428 heads costs? Could anyone help me out with an estimate?

Re: 390 with 428 heads

What is the casting number?
The 428 CJ head has a chamber of 73-76cc and intake valve of 2.08" versus a 390 chamber of 59-62cc and valve of 2.02". I don't see much value added there, myself.

Putts drives a 1965 customized Galaxie. Rebuilt 390, 4100 electric choke on a Performer, MX, AC, PS, PB w Scarebird front discs on Cragar 17" S/S.

Re: 390 with 428 heads

Depends - 428CJ is C8OE-6090N - and a good flowing head - essentially a recasting of the 427 LR head.
C8AE-6090H (the 6090 is not cast into it) heads are 428 passenger car heads, also used I believe on 390 passenger cars, ok but not as good as a CJ head
C6AE-6090R (the 6090 is not cast into it) heads are better I have heard than the C8AE-H but not as good as a CJ head.

Aftermarket heads are typically better than all the above.
