Smallport or Bigport

Postby 20v_rollaboy » Sun Jun 15, 2008 8:25 pm

Sorry if this has been covered before, and I tried a search but didn't have much luck.

I need to know if this head is a big or small port. Ive been told its a bigport, but then Ive been told they should have a external oil drain??
