Jim, The KB192 pistons are for a 289. The stock pistons are sometimes used in the strokers to save money and machining costs. Nothing wrong with doing this since the KB pistons are good quality. The do have valve reliefs cut in them already so you should be able to go to at least a .550 lift without any danger of hitting the piston. In my opinion the engine should be taken apart to check all the clearances and deck height to the piston top. Since you replaced the flywheel you should have everything rebalanced. If the builder added or subtracted weight from the original flywheel you could be way out of balance. I know this is a real setback for you but at this point I would play it safe. It won't cost much to have everything checked and put in new bearings and gaskets.

PS. If you were closer I would check everything for you for free. I hate to see this happen. Unless you feel like a road trip!
