[Tinker51]

Does great work for a fair price and has stood behind his work. One thing you have to be prepared for is that he is brutally honest and will tell you what he thinks. As he is going through a pile of parts he will say something like "this is good, this is crap, I can make this work if you really want but something else would be better" etc. etc.
Balancing, head work (verified by a flow bench), dyno. Give him a call.
