oh yeah... ive had valve decide to make 2 pieces instead of one...and i was travelling down the highway at 65mph when it happened... tore the sheet out of the cylinder and made shrapnel out of the cast piston that was in there... i wont use stock 2 pc valves in a new engine, whatsoever... No matter what he decides, i hope he has the best of luck with it... nothin worse than bad luck with these things...
