Why does it have to be a Tall Deck? The price on the only one of the two (427cid) that matters has been (over)inflated, due to folks that swear by their supposed strength and ability to build cubic inches, neither of which are in your requirements list. A running, "large oval port" 454cid out of a '70's-80's Dually ($300-500) would serve you better, better packaging, better breathing, and only a cam swap away from fun. Tall Deck heads are all done breathing at ~4500RPM, pistons have four (that's 4!) piston rings, negatives>positives. Yuck.
