Jason In Texas: I think you missed the point of this posting.
This posting is about new heads that need to be machined out of the box.
Your Brumfield head looks to me that is has been on your vehicle for years.
I understand that it's warped, looks to me from overheating as I mentioned in my earlier post.
Really doesn't have anything to do with the initial posters concern other than you resurfaced a Brumfield head and the pictures to prove it after it's been used.
Drilling the steam holes in the center didn't help either as Brumfield always spec'ed an R1-R3 gasket not Model B.
