1967 Plymouth Barracuda Coupe

Picked up a 5.7 Hemi in fort collins and A518 trans in Denver this weekend for 450.00
So far one of the heads is to warped to reuse but the short block is machinable.
Does anyone know of a shop that would rebuild the 518 that I have and not just do an exchange. I am in Colorado Springs and thought I would see if anyone can help.
Thanks,Joe
