Need flow #'S for LS2 heads

[cuzimoto]

I got a set of LS2 heads from an 05 GTO with 26K on them. Looking for the spec of the chamber volume and flow #'S. I found all these specs for LS1 heads, ZO6 heads, and just about every thing else but not stock LS2 heads. Any one out there know where to look. Thanks

I am under the impression that the heads that came with the ls2 are the 243 casting which are labeled ls6 heads. most sites and companies use the ls6 labeling so that might be why your arent finding exactly what you are looking for.

That's funny. I know that the LS2 heads are based off the LS6 butt didn't know they were identical. That would explain it. Looks like I may be looking at some cheap Hp.

Yeah LS2's use the same castings (243) as LS6's, the only difference is the valves and springs.

thanks for clearing that up. I already have 926 springs to accomidate my cam. Good port job and some gaskets should make for a good upgrade for little dough. I didn't want to spend good $ on heads cause I've got a Lq4 to build and want new L92 heads for that butt don't fit on LS1. Trying to be cost efficient. Nice stance on that formi!!
