Magnum Exhaust Valve Replacement
 
Looking for a set of 6 exhaust valves for my 478M heads. I have been told that Cat part number 016305 is what I need, but that doesn't show up as a good Cat part number.

Anyone have a different Cat part number or know where I can find a set?

I just replaced the exhaust valves on my 401M. I used exhaust valves for aftermarket 460 Ford heads. The stems are smaller and the valve guides had to be changed out with bronze guides to fit. I will look over the weekend for part #s and let you know. Dave

Same diameter valve? Correct length?

Same diameter valve. The length is a little shorter and the retainers and locks need to also be changed to fit valve. Used valve caps off of diesel motor to make up the difference. I will get to the shop over the weekend and I can be more specific. Dave

Are these solid stem or sodium filled?
