Good, reliable machine/engine rebuild shops for the RB series motors

[RedlineGT]

I am looking for some reliable and knowledgeable shops out there that can rebuild and machine a RB series motor and know there way with it. If this topic has been discussed before, please re-direct me and i would be grateful. I have searched and did not find much substantial info.

Thank you for your time

fyi - i am thinking of getting my RB20 rebuilt and have some head-work done to it, hence my search for a good shop. No time or tools to get it done myself. So i am ready to pay the premium for my time
