These heads will be part of a "top end" package for serious racers. The package will include the heads, cam, pushrods, Crane Rockers and port matched FAST 90mm intake/throttle body.
All of this is info is preliminary. Once the dyno proves that the package works well, I will list it for sale on the web site.

Those look nice..... any possibility for those without all the other goodies in case we would like to use them for something like a stroker engine without the fast intake, or already have one maybe.

I bought a set of 2700mile LS6 heads off a 2003 Z06, did my own porting and got Bob Bruneau Machine shop to open up and cut the valve seats for 2.02/1.575 Manley valves. Here are some pics of the intake and exhaust (but most of the work was in the bowl area...no pics unfortunately). I am VERY happy with the final result and the cost was comparatively low.
