Changed supercharger and lol gaskets ,water pump ,new thermostat the first day drove back to Savannah for work ran fine.Later that day ran to the store temp shot up ,sounds really rough when it starts ,soo I'm thinking new head gaskets and maybe new heads ???? Can anybody help . Oh flushed radiator new coolant the green stuff and some seafoam in gas tank.. Tell me the seafoam can go in the gas.
