Sounds like a pretty good shop then. everybody makes mistakes, but those who back it up are usually the good guys. Don't worry dude. It'll be mean again. Keep us posted. I bet dollars to doughnuts that valve is bent, too.
drove down the the machine shop (Chuck Speed Center AZ) and they broke the entire head down infront of me... all the exhaust guides/valves were galling and ready to stick... so looks like they are getting all new Ferra exhaust valves because the SI valves that are in it (supplied thru Clifford) as supposedly have rumors to be Chinese junk...
so they are covering it and now i have to get another damn intake and head gasket!
