mine was 270 across

I would worry more about it if the numbers did not match up.. like 80 on 1 cylider and the rest were 180.
Try to do a leak down test if you are really that worried about it.

Some testers blow. I did 180 across in my cheap autozone one then did 230 in my Snap On. Just look for consistancy and you'll be fine.
