Default External Torx Valve Cover Stud Size?

This is for an early '86 with iron heads. Does anyone know the size of the external torx valve cover stud?

Thanks!

I went there and compared with a standard torx. Looks to match a T-25, which indeed converts to E5. So if anyone has this issue in the future, you've got two votes for E5. I definitely trust Joe C, so there ya go...and good luck!

Thanks Joe C.!
