Yeah I am not driving that far up to get studs done that is why if anything else I will have to do them myself or find someone in the area who I can at least talk to about it so I have a clue. The valve springs seem to be alot hartder than studs its just this bottom tapping and maching the pedestals has me at a lost
Taps are typically run by hand not on a drill...
