202 valves for J heads

Hey Larry, just though I would give you an update on the valves you gave my son for his 360. The engine was bored 30 over, the heads were ported and polished and gasket matched with the 202 valves you gave him, a purple cam 484 lift was installed hooked to a 904. The rear end is an 8.25 suregrip ungerneath a 72 Dodge Dart 4 door, Orange with a black vinyl top. It will burn the tires off, He is having the time of his life. He smoked a late model Camaro a couple of weeks ago. Thank you so very much.
