Re: Exhaust port height comparison

I replaced my 1972 402 with a ZZ454 about 10 years ago and while I did not measure the two to verify I believe there were no differences in height. Only issue I had was the threads on the drivers side head A/C bracket mounting were one size too large, so I could not use the factory bolt and there were no provisions for the factory starter brace. All in all no big deal for the overall ease of the swap and improvement in performance.
