FS: 5.3L heads
FS: 5.3L heads These are a set of very lightly ported and polished...barely noticeable...stock 5.3L heads. Heads were recently flow tested and I had .010" cut off them. Beyond that .010" I do not know how much if any has been milled off as these heads were on the car when I purchased it. Heads have 2.02/1.55 valves (I believe) and also have REV Xtreme Dual valve springs (good to .650" lift).
Flow Numbers in 28" water
Lift Intake Exhaust w/o Pipe With Pipe

.200 126.84 121.32 124.17
