Kb190 Pistons And Eddy Heads

The biggest thing is the deck height. If the block was machined properly, the piston would hit. If the decks were skim cut, the pistons are lower in relation to the head... But you have to know how much lower. If you have piston to head clearance tighter than .040" (what the special gaskets for the RPMs compress to...) then you may have a problem. My guess is you're fine with the open chanber heads.
