Are you looking for 455 heads? As far as I know all the combustion chambers were the same size. Unless you compare small block olds to big block olds. The ports were slightly different but nothing that a die grinder couldn't fix.
I might have a set I would have to look.
Have any pictures of the Omega? Helped a friend build one years ago. It was a pro street type with a tilt front end. Last I heard of it was he sold to some one in Grimsby.
A good person to ask would be Brian Davies at the GO Shop in Peterborough. I don't if it's still open or not. He used to race Oldsmobile way back. Had 70 w-30 with a w-27 rear end in it.

After 72 they go to 78cc, in 73' they had a mix of 64cc w/dish pistons and 78cc w/flat tops but 72 and earlier 64cc and flat tops were the preferred combo.
