Heads for boost
Heads for boost I'm running a rear mount turbo, and a low-comp forged shortblock.
The current heads are first generation TEA 5.7, and should have me at 8.4:1 compression. The setup is making 543 rwhp at 11 psi today.
When I spec'd out the pistons with SDPC, we chose a dish that should work out closer to 9:1 with newer better heads later on. That was about 3 years ago. I'm ready to start thinking about those heads now, but am not current on the latest and greatest.
I'd like a few thoughts on pro's/con's of the top 4-5 heads that would be suitable for a 15 psi setup making around 650 rwhp, that won't make my compression go sky-high, but will flow even better and will bring the compression up some.
Cam is a 224/228 .581/.588 on 115. Intake is ls6, but I'm open to ideas there too...

Can't beat any of the thick decked AFR's for the $, yes, they're expensive, but running 15+ psi, I think it's worth the extra few dollars for some peace of mind. They flow well, and will last a LOOONNNGGG time on that motor and get you where you want to be!
