Can some body give me direction with my issue. I have to replace all valves but i know Steel is the better option which is what i am going to change too. But my problem is. Will OEM 2000 426 valves and sprigns fit a 2002 head with out any issues. Has any body done this. I dont rev the engine hard so changing from titianum to steel wont give me any problem. Any info would be appreciated.
