Can someone provide a list of the years that stovebolt engines ran domed pistons? Also was there a different cylinder head for those engines, and how much compression loss could I expect if cast iron domed pistons were replaced with flat topped aluminum ones? I'm planning to "resto-mod" a few 216's by boring them out and installing 235 aluminum pistons. Should a 60 overbore compensate for the loss of the piston dome on the older engines? Also, did the spray-oiler 235's have domed pistons?
Thanks!
