Both Patriot and Livernois have a great deal on LS6 heads right now. Talk about a buyers market.
I'm building a LS6 right now and I'm fortunate enough to live close to Livernois, so I dropped my heads off to them the other day. These 243's will flow good numbers. I'm having the head fully CNC'd and milled then reassebled with TSP double springs and Ti retainers. My intention is to keep air velocity as high as possible within the head. I've taled with all of these guys and you cant go wrong with any of them, just great customer service and the knowledge to go along with it. So get out the credit card and do it!

 

I read that 243 heads can run less spark timing than 241 heads and still make the power. That should decrease chances of detonation.

9 second car with stock 10bolt and trans is amazn

What exhaust are you running? THe edelbrock stepped headers with dual 3.5" cutouts should help add some noticabe power.

 

Ammazing is right. How the heck did you get to a 2750 lbs race weight??

 

I'm running Jet Hots with 18" extensions at the track. I run 2.5" duals on the street but those are going in the trash for something else. The 10 bolt does have axles and a girdle.

The 2750lbs for next season shouldn't be too hard (note that's the cars weight with a 1/4 tank, not race weight). The car was 2850 last season. I have done all the usual stuff plus some more extreme stuff. Like cutting 14lbs of wiring out of the stock harness, taking out any unused interior brackets, cut off the front of the frame rails, no power steering, and the list continues. This season I'm addind a pin on hood, K-member, plexi side windows, light weight carpet, 10lbs Kirkey seats, and some other stuff.
