L76 Intake on a stock LS2??
 

Is it worth any gains without L92 heads or even match up properly with LS2 heads?

Ports on L92/LS3 are not the same as an LS2 so the L76 intake won't line up.

Thanks Tom. So that's why people use the L92 heads with that intake I assume.

L76 / Ls2
 

Well, that and the fact that right out of the box, they breathe about the same as some aftermarket LS2 heads. If you can get everything at a decent price, it's one of those more-than-worthwhile swaps.
