Machine shop refuses to install exhaust valve seats

I agree with HEMI446, maybe the guy is an idiot or hack OR maybe he doesnt want his name on them because if they take a dump its his fault, not OP's for trying to revive scrap. If its not for a numbers matching build, why on earth would you not just get a modern set of heads with better quench, larger valves, hardened seats and MUCH better runner volume. I am basing this on machine costs on West Coast in smaller town but guessing close to $300 each by the time the dust settles? Thats using old parts, not new. For a couple of hundred more you can have all new parts and a huge jump in performance. Bare EQ's are $600/pr and assembled with fully polished valves, retainers and locks are $945 shipped to your door. These have 1.92 intake and 1.6 exhaust that ootb flow better than ported 915's. They come with LA intake pattern so you can use your existing manifold.
