I'm looking to gain about 1-2 tenths in ET.

What are the differences & can anyone post what the approximate gain would be in HP & TQ going from 2000 LS1 to 2003 LS6 heads..?

I can get the LS6 heads ported if needed, but again, I am only looking for a nominal gain, nothing too radical, so the AFR 205's would be out, and possibly even the port job.

I'm thinking just the swap to the 03 LS6 heads might do it, but not sure how much better or the gains they give compared to my 00 heads..
Currently running the TR 224 cam..

Thanks!

should pick up 10-20 RWHP with your Cam. The LS6 heads will increase your compression by .5 and produce better low and mid lift #'s then the LS1 heads. With all the good bolt ons, you should obtain the magical 400 mark. Most 224/224 guys fall around 375-395 with stock LS1 heads.

If you do the swap, you'll need to retune.
I would say YES you should gain at least .1>.2 in the 1/4

Any difference between stock LS6 heads & Z06 heads?
I might be able to buy Z06 heads off a buddy....

LS6 heads = Z06 heads

To help you better understand the LS6 vs. ZO6 question: LS6 is the engine the ZO6 (suspension, also a model) Corvette had.

DONT waste your money on that swap......
I'd buy AFRs or a set of Patriot S2's as this would work MUCH BETTER than a out of the box LS6 head,your TR224 will work awesome with the AFR 205 or the Patriot S2's..

Joe... No rollbar in my car.. I can only go down so much before I get expelled from running.. Another 2/10 would be perfect...

If I wanted a bar, the AFR 205's would be a done deal..

Might still go that route, but I'm not there just yet..
