I just picked up a set of complete 243 heads from an LS2 (~180K miles on the heads). My plan is to just hand polish/smooth the ports/chambers and install a set of stiffer springs for a mild head/cam swap. I'm not interested in having them CNC ported/larger valves installed (HP goal does not warrant the added expense).

My "concern" is reusing the valves. Should I replace the valves or will they be fine after a valve job?

I had a head shop reface mine. I figure, why take a chance on leaky valves.
I would rather have them seal up like new. Use new valve seals too. They are not expensive.
I don't think it is a good place to cheap out.

Just take the heads and valves to the machine shop for a valve job and you should be good to go.
