LS6 Head milling question

What do I need to mill the 2002 LS6 head to achieve a 10.8-11.0 compression ratio on a stock 346 CI LS1?

Thanks

Stock ls6 chamber is 64cc so .020" should get you 61cc for 10.9 to 1 comp. Valve shape plays a part in final chamber size.

Yup, sounds about right.

I had my LS6 heads decked .040, my chambers are running between 59.5 - 60.0. CR is around 11.1

Re: LS6 Head milling question

I have the same question as Ireland31. But my head is CNC ported from SDPC and has 69cc.
I'm afraid that I have to mill it .060 to get 10.8-11.0 comp.
