That's what I've heard as well.
I've talked briefly with smith shop Kirst uses and a very nice informative fellow got me a good piece down the road with some things to look for. We were able to eliminate a few things. Problem is he is on the east coast and I'm on the west and Im one those few lucky stiffs who still has a full time job. And they don't work weekends... So I either call in sick to finish this project or find help elsewhere. I'm hopeful I can get some help here.
I'm also thinking hard about buying new oversized parts and seeing if I get close on my own, at least that way I don't screw up what works well with the original cylinders.
