My old school 340 upgrades and results.

Don't think I bent a valve. No air leaking when pressurized with air . Also while searching my treasures aka old boxes of junk I have collected I found a new set of intake gaskets for a magnum. I placed them on my Performer RPM that is scheduled to go on and the ports and holes all line up. No provision for exhaust cross over which I would be blocking off anyway.
