Machine shop visit

I took the block to the local machine shop for a professional assessment about what it needed. I was there mainly to have the machinist look at the exhaust valve seat, but he gave the whole thing a once-over. He thinks the seats are OK. But, after seeing the intake valve his first impression was "new valves, since it's apart." This scared me a bit since the machining cost will be "about $80 per valve" (and there are two). That blows my thumb-in-the-air machining budget of $100 out the window. Also, he recommended a re-bore as well at a cost of $50 (more on that later).

After the machine shop I took the block into work for some more measurements ...
