Thanks for the info, guys. These really are some top notch heads. If I was staying NA, these would still be on my LS1 RX7. I know it's oranges to apples, but there were a few LS1 RX7 guys that were running 10's @ 125-128 mph NA using these heads. No nitrous.
Like I said in another post, I'm a turbo engineer, so the urge to boost my car is just too great to resist!
I calculated a static compression ratio of 11.46:1 on a stock LS1 bottom end with standard GM MLS gaskets. The dynamic compression was a little high on my engine using a relatively small 232/234 cam. A cam with a little more intake duration will LOVE these heads.
