I have only used three machine shops in the Denver area:
The Block Shop, They are on 2373 South Plate, near SanteFe and Evens.
MadCap racing engines, 7895 W14th, Lakewood
American Automotive Machine, Don Hackenberg, 8672 Emmerson Ct, Denver.

I have not used Ridge Reamers?

All those listed above have torque plates for Mopars. MadCap has the lifter bore fixturing, if you need the lifter bores corrected and bushings installed. They are usually really busy with race engines, so it may take several weeks to get your engine machined there.
The Block shop does nice work and they usually will have a block machined in about a week or less. They can align hone the mains, but they do not align bore / fit aftermarket main bearing caps.
Don Hackenberg at AAM specializes in Mopar engines. He has built alot of Mopar race engines.
He runs a small shop, so he may be busy?
Don got me a good price on fitting my BCR aluminum main caps and girdle.
