I am selling my heads off of my engine, that is currently making 800RWHP.
These heads were purchased as Blank LS6 Stock heads and had a Stage III port job done on them.

They have a 73cc chamber cut in them with the -15cc dish piston makes 9.8:1 compression. I purposely went with a higher compression. They are preped and ready to install.
They have the 2.080 Intake and 1.60 Exhaust,
They have the 4.125 bore set for a 427.
They flow over 320 on the intake and over 225 on the exhaust.

The 800 rear wheel power confirms the quality of the heads as I am making that power on just 10lbs of boost. These heads are proven, you can see the dyno graph that was made with these heads at www.perigee.net/~lunapark.

The heads will come with polished, and newly lapped Rev valves, and new springs, and new 1.7 ratio rockers.

I am selling to do something different. I just have not decided what as of yet.
I will sell the heads for $2000.00 shipped to anywhere in the US. THese heads were $3200 to build. Shipping will be via UPS. Payment can be made via paypal.com, cashiers check, or MO or personal check, NO CODS.
