Our flow bench was a bit generous. I sold the heads to Paul Knippen and on his bench they were were 278-282 at .600" lift.

That's cool Steve, I didn't remember you doing that with the crank. That's back around the same time I did mine.
I would have done a 455 crank instead but dad used that in the 428 block and left the 428 crank laying around.
Back then we were just using parts and pieces left over from other builds LOL
