Thanks guys!  The list consensus confirmed my original understanding.  This
person woke up too early this morning and was a little confused.

Thanks again!

This is not true, the compression he is referencing is the pistons, not the
head, both the 3B and 7A have about 37cc combustion chambers.


>Hi guys-
>I was talking with a local guy who is said to know a lot about Audi tuning
etc. He said that putting a 7A head on a 3B bottom would have a higher
compression ratio compared to normal 3B. He said it would increase from
9.3:1 to 10.3:1. This was not my understanding. Can anybody confirm or deny?
