SOLD WCCH Stage 3 LS3/L92 heads $1700 shipped

SOLD

Low miles (~5k) Stage 3 WCCH LS3/L92 heads. These go for $2600 new and there is usually a wait associated with getting them.
Stage 3 specs:
280cc intake runner
2.20 Intake valve
1.60 exhaust valve
Valves are both solid stainless valves. When I had them done, there wasn't an option for hollow intake valves in the 2.2 size.

Chambers are 72cc.

Springs:
Intake
Installed height: 1.750
Seat pressure: 163
Open Pressure: 450
Open height: 1.180
Coil bind: 1.050

Exhaust
Installed height: 1.800
Seat pressure: 154
Open pressure: 439
Open height: 1.200

Comes with springs, retainers etc. No rocker arms included. The only thing I cannot find at the moment are the rocker stands (GM Part number 12600936). I think I know where they are and i'll include them if I find them. Otherwise, they are $10 each or less.

I used these heads for a Ysi build and made 825rwhp at 17lbs with ZERO signs of head lift.

Flow data on 4.155 bore.

I asked Richard at WCCH what the difference in flow would be from the tested 4.155 bore to my 4.070 bore and he said it was minimal.

1700 shipped/insured.
