Engine compression question.
So I'm at the gas pump last night and a high school kid in a tricked out VW is next to me and starts asking a whole bunch of questions about my car. I could answer everything except the compression ratio

If the heads are lower, like 64cc's,than stock then the compression will be a little higher if the cc's are larger like 72cc's then it will drop the stock compression.
Stock compression for an '03 is 10.0:1 (10 to 1)
