Hey peoples, I know this topic would have been posted up previously, but typing in A8 in the search box brings up a ****load of threads. Can someone just give me the quick difference between A8 block compared to the A6. Or is it just the fact the the A8 came in the bt1's??? Cheers....

A6 series 2 blocks have the holes there, but the series 1 blocks don't.
