Specifically, the heads are GM 853 heads that originally came off a 99 Z28.
I sent them to Phil and they did the high compression 219cc CNC porting. Chambers are 56cc, which will be 11:1 on my 6.0. This was $1,195.00.
These heads have the BTR .660" Polished Dual Spring Kit w/ locators, viton seals, & Titanium Retainers. This was $300.
SOLD
Thanks,
Marc

Sorry, I think I need to clarify; yes the heads are milled to 56cc, but I was putting them on a 6.0 with flat tops. When I talked to Phil that setup was going to be 11:1. I'm guessing with an LS1 it would be higher. Not sure though since I don't have a 346 LS1.

Any time. I inquired because I really wanted to buy these. LOL. 11.8:1 is way too high though for my little daily driver ls swap. Good luck with the sell on an awesome set of heads.
