John I had a set of the Domed pistons in my original engine and had problems with finding gas that had enough octane to run the car properly. The compression on the domed pistons, I think, is 8.5 to 1. If you don't shim the heads you may run into problems with knocking and pinging on lower octanes. Even 94 octane from Sunoco gave me problems going up hills. Just my 2 cents :) Good luck! ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
