Anybody have any experience with the 50 cc chamber Motown 220 heads? Do they require special pistons like the Darts? Want to run solid roller 260/264 .650 lift cam

If they have not relocated the valve centers on those heads then I would at least assume your likely to need deeper valve notches in your current Pistons due to those 50 cc chambers!
