Default c6 headers in c5

Fellas I thought I read it somewhere before, but will c6 headers from an ls3 work in a c5? 1 3/4 in kooks or lg's?

I'd recommend you call Kooks or a forum vendor that sells that brand and ask if they will work.

If you have a ls1 or ls6 they will not work no matter what

Different sized and shaped ports, yes?

I think that the C5 BAT WING OIL PAN also causes fitment issues.

I'm using the same TSP LS1 long tubes from my LS1 on my LS3...
I don't know that swapping the other way will absolutely work, but it doesn't seem unreasonable.

It might. But there are lots of factors. I'm using LS1 headers on an LS3 in a C5. And yes, they work just fine. But there could certainly be differences in LS3 headers designed for a C6 that could run into interference in a C5.
Best bet: if you've got them, try them. If not, contact the manufacturer.

If you used the LS2 oil pan the C6 headers might work. But then doubt that the mid pipe will fit.
