How deep is the induction hardening on magnum heads - can I do a valve job?

kielbasa said
Hi guys, bought a pos '97 ram with a crappy running 360 to use as a plow truck. Pulled heads and the exhaust valves and seats are HORRIBLE, was able to clean up the valves and still have some margin left, but I worry about cleaning up the seats and going thru the hardened portion - I have no idea how thick that is.....I'm guessing 50 thou, give or take?? Anybody ever done a valve job on a magnum head? Thanks for any info!

as long as you are not hogging out the bowls, and/or putting bigger valves in, you can grind away and clean up those seats. I would hesitate to take it to a shop that uses a Serdi type cutter, but I would recommend the old school taper pilot grinding stones job.
