Maybe this is the wrong place for this, but I was just curious. I found some 32 valve heads that show to fit the LSX platform. Just wondering how these would perform for the price???

I think its a stupid design because there is still only one cam. The valves just open at the same time.

 

For the price, not too well but they are seriously interesting!

 

Yeah the price is a lil steep, but I bet they breathe pretty good!
What intake these require, L92?

 

It says LS7, so yes, an L92 intake would work.

Edit, Incorrect.

"Both the Intake port and the bolt holes to mount the intake to the heads are in different locations on the LS7 heads -vs- the LS3/L92 heads."

Sorry for the misguidance.

 

They been around for few years. Guy that makes them is know to take your money and never ship your heads to you.

 

Many other 4 valve engines have both valves open at the same time.
L92 and LS7 intakes are different so no an L92 intake will not work for it.

 

you'd have to be pushing some serious cubes with a huge intake & exhaust to really get any benefits from these heads anyway

 

Eh, that's not always the case. More valves mean more valve surface area, which means that much more a/f volume can flow past them. And we all know that an engine is just a big air pump, so in turn, that usually means more power.

Now whether or not the increase in output justifies the cost outlay is a different matter...

 

ok i may be blind, where is the second row of rockers.
i see the row for the exhaust, but where is the row for the inteak.
i see the springs for the exhaust, are the inteak springs under the rocker rail.

it looks like a duel overhead set up for cams but im just not really seeing how
duel rail rockers work here.
