FS: WCCH 13.8:1 High Compression LS7 heads Category: Accessories
Price: $2700
Part Fits: Corvette
Location (State): TX
Item Condition: Used
Shipping Information: Item Can be Shipped
Engine: LS2/LS3/LS7/L92/LS9
LS Engine?: Fits LS Engine
Specs on the WCCH heads:
13.8:1 static compression
Bronze Intake and Exhaust valve guides
Rev SS Exhaust Valves
Stock Ti Intake Valves
Angle Milled .150
This setup is built for E85 and made 550rwhp/510rwtq on a Mustang Dyno which tends to read around 12% lower than a dynojet. I am debating a switch to boost and will need to get back down to a stock compression head. I paid $2060 for the port work, bronze guides, and ex. valves for my stock heads. These heads have approximately 1000 miles on them since getting them back and installed from WCCH. I am looking for $2700 for the heads.
I have the stock springs, retainers, etc...for the heads that will be included. I will be keeping the valve spring kit that is currently installed to be paired with my current cam setup. Here are some pics of the heads when I got them back from WCCH.

New price $2400 including complete valve spring upgrade kit with Patriot Dual extreme .650 lift springs, retainers, etc...all you need is a set of valve lash caps and then bolt them on.
This is basically the price I paid for the head work and the valve spring kit. $2060 for the head work and $310 for the spring kit. So you pay what I paid and you get the LS7 heads for free.

The LS7 head was angle milled .150 lowering the chamber volume to 51cc on a stock LS7 bore (4.125/96.01). I ran a stock LS7 MLS head gasket (~.055) and stock LS7 pistons, but if someone was running a -cc piston, thicker head gasket, etc...you could obviously set the compression where you wanted it. You could run these on E85 or pump gas, it's all in the tuning.
