I guess I need to take out an exhaust valve and see if they have the pressed in seats or not. They heads are going on a mild 350 bored .060 over. It's not a daily driver, just my fullsize truck I use for hauling and towing once in a while and pulling our boat. How can I tell if they are GM factory heads or aftermarket cast iron vortecs?
