Steve,
I don't question anything you say... I'll try to ask the question in a plainer manner.
"Who is the original manufacturer of the pb guides you use? It is probably a combination of raw stock mfgr. and a machining company. We are not questioning if they are good or not... by all accounts they are good or at least good enough.
If you say... that you have been in business for years (and I know you have) and have finally found out a good source for valve guides and would rather all the other valve job shops not know. That is perfectly fair. That makes it a secret and is the point. If all the valve job shops want to keep this a secret, that is also perfectly fair. It is ok for you to respond with " I want to keep this a secret so quit asking".. The reason I'm asking is a friend just pulled his 3.2 for a top end rebuild and we want to have the machine shop use the latest thinking on best materials. I think that is what this forum is all about. In no way am I trying to get into some sort of pi__ing match on this just trying find out some info.
