Yes, there is a cut mark on it.

Looking at the website for BEST they list the 6380S seal as "67 400-428" ??????
Someone made a mistake. Also they list a seal that combines 61-66 389 (are they not the same as 400?) with the 1950s 316 and 347 engines. Didn't those come with smaller mains and why are 389s and 400s not listed together ?
Better to buy it from Butler, at least they know how to list the Pontiac engines.
