I have an unused set of GMPP #88958665 LS6 CNC heads for sale which are still in their original boxes. These have been impossible to find for a very long time.

Asking price is the same as the MSRP was from well over a decade ago @ $1,149 each and sold as a pair only (total is $2,298 for the set). My preference is not to ship, and these would have to be picked up in the Metro-Detroit area (I can deliver / meet "half-way" for a reasonable distance).

Specs are as follows:
2.00" hollow stem intake valves and 1.55”sodium filled exhaust valves
210cc “Cathedral port” intake ports
70cc D-shaped exhaust ports
65cc combustion chambers
Note: .570" max valve lift

I completely understand not shipping. I wish I were closer. Good luck with the sale.

"I know what I've got."

The world has moved farrrrrrrrrr from LS6 being noted for anything in a decade.

That said, bump for this thread. When i get reinstated on fb its going on "Which Corvette is best Corvette"

I get it... They're old tech and a lot has changed in the last 15 years. But they could be exactly what someone has been looking for.

True. Someone will be happy to pick them up. Extra bump.

Another free bump. Yes, they're older school. So are 1957 Chevy convertibles, and they're still in demand. I think these heads, with the OEM lightweight valves, are still looking pretty damn good, especially when they're NIB!!! Betcha they flow 315+CFM. All it would take is some new, stiffer valvesprings, then a .600" lift cam, and watch out!!! GLWS.......
