i talked with edco and they want 570 bucks in labor to fix my head so i think im going to buy a new one. i was wondering how hard it is to install valves into a new head. i have a valve spring commpressor what other tools would i need? i dont really have the money to buy a new head and pay to have valves installed along with the other parts i have to buy for the motor. edco was saying it would proboly be 300 + to install valves and springs.
