Default New GM heads...

What's the scoop on the new LS7 heads and the new truck head for the smaller bore??? From the flow numbers I've seen they should kick major butt. I assume they'll work with existing headers, but require the new intake that matches the heads.

I've been thinking about getting a good set of aftermarket, but want to wait on these to see if they are as good as I've heard.

Does anyone have a details on price, flow, deck thickness, and availbility???

yes, they are bad ***, basically a c5r head. you'll need a new intake though as the ls1/ls6/ls2 intakes wont bolt on. not to mention unless your building a big bore motor forget about these heads. on a 346 go with some AFR's.

check the ls2 section or use google to find all your answers.

But that's just hocus pocus, right?

Yeah already heard that Brian has a set of the truck castings... might be the cats *** for new castings with the LS7 style port. Too bad they are circa 2006-2007
