Napa Machine Shops?

Drake,

Leave nothing but what you are having machined. :)

Next up, find a shop with a reputation that preceeds them, not from a friend running 14's. If you see 15 or 20 20K and up engines in the shop, it has a dyno and seperate rooms for head assembly, block machining, engine assembly and you can eat off the floor, that's a good sign but not the end all.

3rd deal is find a shop that's been around more than 20 years by whatever name.

4th up is learn to use a mic, inside, outside etc. ALWAYS double check the work. Even the best shop can have a bad day and a reputable shop will always fix there muck ups, even if it means they find you a new block, crank, whatever.

Let me tell you a story about a machine shop I was refered to after my regular guy got an exclusive contract...... The block machining was great but the drunken head guy mucked up my heads bad......Not worth half the price I paid. He left lapping compound inside the ports, there were hunks of metal splayed out from his "valve guide replacement", three valve springs weren't even seated, valves were way too deep, etc..... This was from a supposed "Formula 1" race shop with a travel semi. Nothing but wanna be euro-trash, lol. Thank God my guy quit the exclusive NASCAR stuff... well I'm glad, he misses the money but not the travel. :)

In conclusion, the local NAPA would have done a better job on the heads than the "Formula For Disaster" and I've met a guy in Witchita KS that does beautiful head work on Porche, BMW and Ferrari heads for SCCA racers but his shop looks like a shack from hell.....
