headers fit ls2 and ls3

I know this has probably been mentioned but I have searched and have not found an answer yet. Do headers meant for an LS2 fit an LS3? I read somewhere about the ports on the LS3 being shaped like a "D". Is this going to be an issue with LS2 headers?

Thanks,
Shaun

LS7 is close, depending on the header. Ours are close, and we modify C6 or C5 headers if a customer is planning on or upgraded to LS7 heads.

LS1/2 heads to LS3 heads is not enough make a difference with our header, even though the port height is higher on the LS3/L92s.

Also, the LS7 headers fit on the LS3 for obvious reasons (same heads). You just need a different X-pipe if connecting to the stock or 2.5 inch exhaust.

But no issues putting LS2 headers on the LS3.

They will fit, bolt up physically yes, but the port height on an LS7 compared to that of an LS3 is not the same. There is a big enough difference that the headers need to be modified.
