340 Heads intake valves

Don't have valve seat inserts fitted to the intakes if you do you won't be able to fit them to the exhaust which you should do. Have them crack tested before you spend any money on them.

Is it necessary to run 273 rockers with the bushings? I have 15 without, and only 1 with a bushing.

My guess it the one needed a bushing to bring it into spec. No, you don't need bushings. Mopar has a lot of oiling up top which is great for a daily driver!

Thanks. They were all nice and smooth inside, except for one. Would it hurt to try and sand this out, or should I toss it and look for a new one?
