I have a built LS1 with Kooks headers in my 99 FRC track car. I am considering upgrading my heads and intake manifold to LS6 or better. Will the existing headers mate correctly to the LS6 heads?
Yes
Don’t discount getting a set of the 5.3 heads that TSP machines.
They have smaller chambers so there is a bump in compression. They are the stage 2.5 CNC

FWIW there are options like the summit 'as cast' heads. They are similar to a set of ls6 heads supposedly, but instead of refurbishing a head, you're getting all new parts. I think there are a couple companies doing a similar things.

Yep. AFR also has the Enforcer series. Downside: castings are made in China. They seem to be just fine though and are supposedly checked and assembled stateside.
