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?

Do you have a link? Just looked and didn't see anything...

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?

Re: Magnum Exhaust Valve Replacement
 

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?

Re: Magnum Exhaust Valve Replacement
 

I checked out the auction on those exhaust valves, they are the stock hollow stem sodium filled valves, definitely a weak link as they can snap for over revving. I bought some Cat valves a while back that are the same diameter but with smaller diameter solid stems, only issue is the stems are shorter so I don't think they can be used. I intend to replace the hollow stem valves on my 478M in the future, knowing myself being a lead foot. and the fact my 478M was built up to rev over stock specs!

Here's what I did. Used Trick Flow stainless valves for 429&460 Ford Trick Flow Heads. Part#TFS54503212 with 13160-8 10 degree keeper and 748-16 Retainer. The valves are.080in shorter than stock,which doesn't cause any problem with the spring and used a 11/16 lash cap on top to add length,part #621-16. Install Bronze valve guides part #VG-7006R . Adjust rockers for stock clearance. Hope this makes sense. Worked for me to get rid of the sodium fllled valves. Dave

Wonder if the 429/460 valves will work in my 478M because I'm using higher lift valve springs for the custom ground cam, ironically those higher lift valves springs fit Ford 390 applications.

Really? Just a set of performance FE valve springs? Good to know.
