Good point Paul. I think all the beveled pistons I have seen in 455s are aftermarket cast oversized. They show up a lot in stock reman’s.

I was thinking Lee Atkinson on the forum had a OEM set in a 455 with the beveled pistons. But I was mistaken, his are aftermarket oversized with that beveled. FWIW, he has very low compression with his 66 heads and a bigger cam with tri-y headers, and has done multiply pulls on his wheel dyno with it. It runs well, if it is just temporary anyway, the 66 head can work too. Lee’s makes over 300 at the rear wheels.
