Replace stock LS6 heads?
 

I think that I should replace the heads last, but since I haven't seen many cam-only stock LS6 head cars, I thought I would ask for opinions.

I have a 94 Camaro with a stock 6.0L LS2 (the heads are LS6 with solid valves).

It has pacesetter longtubes and dual 3" exhaust for now. I'm using a NW 90mm TB with the stock LS2 intake.

I plan on adding a "small" cam (<230 duration) soon.

Looking at a 205cc AFR head, what are the "normal" gains over an LS6 head?

If I had stock LS1 heads already the choice would be much easier, but the engine came with these heads so I will run them for awhile at least.

I gained 28-rwhp/14-rwtq, by just bolting on out of the box AFR 205's.

Depends on the money you're willing to dish out.
You sould sell those and get at least $1K for them then put another $1.5K for AFRs
Upgrading yours to stage 2 (2.02, 1.57/1.585) will cost you about the same (with CNC porting)

Was this with your current cam, or before that?

Thanks for the reply.
