There is a line of Sealed Power pistons w/a smaller diameter, deeper round dish that have a wider squish band that might be a better option than the traditional shallow round dish pistons- especially the ultra weak shallow dish w/45 degree chamfer around the circumference. Both are shown here
I've not had the time to research this line of pistons fully for application and specs, but I do know the piston shown (H423NP w/10cc dish) has a 1.54" compression height. I'm hoping they also have this dish type in 1.56" CH, and for a 383 SBC stroker, too.
If anyone happens to have this info I'd appreciate a link or the info can be simply added to the wiki (link above).
