I've done searches here and on Tech and can't find the results I am looking for, so here goes:

I am rebuilding my motor thanks to this Hole in block... and I am not sure what I want to do with my heads...? I don't want to spend the money on heads, and but the stock 241's do have 85,000 on them, so I was considering having a valve job done? I have done valve jobs before, but only on lawnmower/OPE engines (Briggs, Kohler, etc) and I don't think I wanna risk doing this myself. What do I need to look for when shopping around, and if anyone has an idea of price, that would certainly be appreciated.
