I recently found out about this company around Colorado- http://www.pfispeed.com/interface.htm . Their prices seem pretty reasonable for what they offer (ie-$3,500 for boring, sleeving, port & polish and engine, plus a choice of hi-po rods, pistons, and gaskets). However, I have absolutely no idea how proffesional or how their reputation is, since I don't know anybody who has worked with them. Anyhow, it can't hurt to call them up and check them out.
