Answer 1

The other answer is good info but I would also do the following services. Have it completely boiled out, cooling jackets and all. Get it back after that and take a small rat tail file and smooth all sharp edges, around oil holes and gasket edges. Replace all the soft plugs,including the ones on the bell housing end with bronze ones and have them pinned. Have the decks checked for flatness. Run a tap thru all the head bolt and main bearing threads. Use new bolts. Have the rods sized, magnifluxed and match ground to the crank journals. Have the crank and rod bearings plasi guaged to verify clearances. Standard Chevy specs are fine for up to 8500 rpm.
On the heads, if your going with a high lift cam with dual springs, I strongly suggest installing screw in studs and guide plates.
As far as pricing, check around, and ask questions, there are a lot of machine shops that are fine for grocery getter cars but not for high performance.. The extra for a quality job is the difference between 40000 miles and 100000. Make sure to break it right by gradually varying the rpm up and down, don't let it idle for at least 10 minutes, you don't want flat cam lobes. . Most of all, have fun!

Answer 2

The cost of machine work totally depnds on where you live. Check a few places to see who has the best price. But best price sometimes doesn't equal best work. Try talking to some of the local garage guys to see where they would send their stuff, that is usually your best bet. As far as what to tell them ...If you have to tell them anything you took it to the wrong place. they will know what to do. Just make sure they don't try to do things that you dont need. You want them to dip it and at least hone the cylindersand clean up the cam and crank bearing areas.. depending on the shape they may need to expand them. Make sure you get them to approve any work before its done. I would take the crank to the same place so that they can grind it to match the block. They would also be the place to get your crank and cam bearings.
