Machin shop/Builder in Denver area

Hi all,

I posted this just before the great crash, obviously it is gone now. I am looking for thoughts on a good Mopar machine shop/ builder for a 1970 340 I recently acquired. It is for the Duster I bought with it, I have lot's of work to do on the body, but want to see what I have to work with on the block. I have it torn down, it doesn't look like it has run in a long time, did have a broken valve, but I can' see any visual damage. Just before the crash I had 3 responses-
Havana Machine- thanks MoparMike
The Block Shop- can't remember the name
Ridge Reamers- can't remember that one either

Just to recap, not looking to build a race engine, but not stock either-- sketchy thoughts, deck the block, balance it, cam up a bit, either new or port the J heads I have, Air Gap intake, TTI headers and exhaust.

Thanks in advance, any thoughts appreciated!

Cheers,
Tim
