imho the pistons on the a14 are as tough a crown as just about forgies, ive seen them bend up valves and pushrods with hardly a nick on them. tomorrow is a 35 degree day good time to know if it pings.

so unless its pinging dont bother decompressing or it will be too laggy, since they are fairly low comp stock anyway, drop the boost a touch with the new gasket and use an IC or water inj and u should be fine. U already have the parts to toughen the weak links.
