Where are you finding TFS 170's for $1,000-$1,100 a pair?
Lets also keep in mind that the TFS are known to need a little work on the valve train right out of the box. I wouldn't be surprised if you were into them $1,500-$1,600 by the time you were done.
$1100 NIB at LMRS my friend before any discounts.

Product Description
Trick Flow® patented Twisted Wedge® 170 performance aluminum cylinder heads feature Trick Flow® revolutionary "twisted wedge" combustion chambers to build more midrange and top-end power without sacrificing bottom-end torque. Here's how it works: Trick Flow® engineers rotated the valves and moved them over the center of the cylinder bores. This optimizes the valve angles and the combustion chamber shape to dramatically boost airflow and allow for a more complete combustion of the air/fuel charge. And, unlike other brands, Trick Flow® Twisted Wedge® heads are the only aftermarket heads that can run 2.020 in./1.600 in. valves with stock, unmodified pistons and performance camshafts with up to 0.550 in. of lift. The Twisted Wedge® series heads are built for heavy-duty use, too. They have 0.560 in. thick combustion chamber walls and fire decks for added strength without a loss of cooling capacity, plus additional support risers in the water jackets for increased head gasket integrity. The Twisted Wedge® 170 heads are designed to be performance replacements for stock Ford heads and are 50-state emissions-legal on 1996 and earlier 289, 302, and 351W Fords (CARB E.O. #D-369-12). All Twisted Wedge® series heads work with most OEM and aftermarket intake and exhaust manifolds/headers. The heads come fully assembled and ready to install right out of the box with stainless steel valves (intakes are backcut for improved flow), valve springs, locks, retainers, ARP rocker studs, and guideplates. Bare cylinder head castings are also available.
