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

allow me to clarify, this is a 300 dollar beater plowtruck with no interior, half the body left, etc.....i'm assuming to have seats installed would cost more than the truck is worth??

A plow truck sees a LOT of loaded, low RPM time. Just the type of operation that needs hardened seats.

I love posts like this where people always want to do a job on the cheap but what they need is the exact opposite. What difference does it make what the truck's worth is as a static hunk of metal?

What's it worth as a good operating plow truck?

All this talk about "it's not worth X, so I am not putting Y into it makes no sense to me.

Either fix it right, or throw it in the ditch.
