If you only shave the head enough to get a clean surface. This will not put the compression as high. The CC of chamber can also be adjusted by careful hand porting. I'd like to see around 9 to 1 for a street turbo engine. It will be more responsive. Just be careful to manage the timing and cool the intake charge.

The J&S sounds like a great system. I know of nobody who runs one on a Chevy inline 6. Hank, you do it and show us.

Snow,
You need to come up with a timing setup that will monitor the boost and adjust/limit the timing. I have made vacuum cans in the past that will hook to a HEI and do this exact thing. One is installed on "PAPS" 32? ford with a supercharged 250. He won a Hotrod track race event in Kentucky with this car. Against V8's.
