Which GM oil filter for 401?

I'm kind of OCD about oil filters and always try to use OEM if possible. Which GM oil filter should I use for my 1963 401 Nailhead?

 

Use WIX 51049 or NAPA Gold 1049 (same thing)

They are superior to the GM/AC Delco filters.

If you insist on OEM, ACDelco 6437462.

 

Same here, Wix or Napa Gold.

 

Checking in for AC Delco PF24. I've also used the Wix filter, which I liked because it was longer, however it suffered from a stuck gasket, which I've never had happen with AC Delco.
