LS4 rebuilt 781 heads FOR SALE!!!
UPDATE.....UPDATE.....4/24/2011 check out post #7
Up for sale are a pair of LS4 781 rebuilt heads. When I bought these, they were going to be used on the 74. But since I have purchased another set of heads, these must go.
Below is a description from the seller when he was selling the heads, the purchase price which includes shipping (which is very expensive, because of the weight) is $510 shipped to your door. I unwrapped one head when they were delivered and they look great. I am not making any $$$ on this, just would like to get what I paid for them. Of course if you can pick up, then we will minus out the shipping costs.
Thanks for looking.............................Tom: )
Local pick up cost.......$380
Previous seller's description of these heads......
"These 336781 heads are some the very best heads available for strong street use for the following reasons: Larger oval shape runners with high flow characteristics, induction hardened seats for unleaded gas, open chamber for better combustion, and exhaust valve rotators for better sealing and longer valve life. These heads are better flowing heads than the ones PAW sell for $399, which are for lower rpm truck use, or heavy vehicles. Mine are set up similar to PAW's but will give at least 35-40 more horsepower, stronger mid-range and 500-700 more rpms. They have a fresh valve job with back cuts on all valves, which flow a lot better as the valves first start to open up, with the best increase around .300 lift. This means much better, flatter torque curve thus more tire burning response off throttle(also a little better gas mileage). On the street, torque and throttle response are what you're looking for, and that's what these offer! All valve have had "Moly Pro-Tek" dry film lubricant baked on, which is burnished into the metal and provides more horsepower, longer valve/guide life and reduces friction. The springs and retainers also have a baked on finish. Both the intake and exhaust runners have been lightly pocket ported, contoured, flashing removed, and intake gasket matched. They have a rough finish, which helps keep the gas from reforming droplets for more horsepower. Valves lapped in and new valve seals of course."

The original description listed them as being "semi-open" chambers. They're open chambers, not semi (290, 215 and 063 castings).
Not a bad price for fresh heads, though.

I think for what these heads are and the work done, that this is a very fair price for these 781 BB heads. thanks for looking......Tom
