429 Big Block
Does anybody know what kind of heads came with the Ford 429 big block? The motor I am rebuilding is a 1973 429 BB that came out of a 1974 Mercury Grand Marquis. I am rebuilding the motor and am about to polish the heads, but I wanted to know what heads they are and if I can put on A460 heads instead of the ones I have now. Thank you to everyone who responds.
