Why not try and find a nice complete used top end that has been set up by a reputable builder. Lots of Redline, Fast, HJR, top ends for sale with cylinders, domes, and misc hardware for great prices. Buy one up, get it bored/honed for fresh pistons and have the same thing for far less.
The niche cylinders are in fact trashy. I've seen them and was the complete opposite of impressed. If you want an OEM'ish cylinder get some used Stock cyls. They pop up on here untouched quite often for $250-300 a lot.
