FS LT4 ported heads and LT4 ported intake

For sale, a set of ported GM LT4 heads (PN 12555690) and a ported LT4 intake (PN 12550631). Zero miles on portwork, heads flowed 262 / 198 at only .500" lift. New 2.02/1.60 valves with new dual springs. Measured 54.0 cc combustion chambers. I got them thirdhand (porter unknown) so I had them flowed locally by an independent shop. Setup for 3/8" rocker studs. Flow sheet is attached.
LT4 intake manifold is ported for 58mm, the usual runners, throttle openings and transition area, ported by Lloyd Elliott.

$1800 plus shipping from Huntsville, AL 35806.
