The flow #s are very impressive, but that's alot of extra valve train wieght too. I would love to see a dyno comparison of these heads against a good ported LS head.

Nobody has ever got a set, so nobody knows if they will actually work.

I don't see that they will live up to billing...

There is not many other things that I could think of being a bigger waste of money then the heads lol. Even if they were free I would not waste my time.

4 valves per cylinder works great on small bore engines with dual overhead cams. They've been tested several times on conventional small and big blocks, make less power than 2 valves per cylinder setups.

I cant see those heads fitting on anything that came from the factory with an gen III/IV motor due to the size of the valve covers.

I heard of these heads years ago and I still have yet to find one person who has them. Its highly doubtful that anyone will post dyno #s or track times.
I believe if this product was any good, I would have known about them by now.

Do some more research on these heads some people ave ordered them and had to sue them to get their money back because of empty promises and never receiving them after a year. Try asking guys with 4 valve heads how they like them after you figure out how slow their car is, like n/a cobras running mid 12's. After dumping thousands into cam's and valve train cobra's still suck just my 2 cents though.

In one of the other threads a guy mentioned he had bought the rights for the tooling and plans for the LSx heads. I don't think anything ever came of it.

I personally wouldnt waste the time OR money on that. You can pick up a set of great, proven heads for less, and still have money to add on to other things.

NRE in California uses them on alot of their engines. They're awesome heads, but pretty expensive. If you get them through a reputable builder/shop like NRE you'll have all thew support you need. Just don't ever deal with the manufacturer directly.
