So there is a cylinder problem? Is it cracked, or scored or warped? What are the symptoms of the problem? Is the car drivable?
I don't know of any shops in Montgomery, but I do know of a good indy in Pelham - Momentum. Of course you could go to the dealer, too, but I am not sure Ingram is very good. I haven't heard much good about them, but then again, you usually don't hear much good about any dealer, especially when they are the only game in town.

Both of these are within the range of the bad balance shaft problems. Is one of these yours and the other the donor car? I wouldn't want either engine as the balance shaft failure is going to cost $4K+ to repair and requires pulling the engine. Then again, the bulk of the price is in the labor (at dealer rates) to pull the engine for the repair, so maybe while swapping engines, you might look into getting the balance shaft on the donor engine replaced. It's about $400 in parts. It's not difficult, but the mechanic does need to know what he's doing.
