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.

Hi J and M Machine. People responding to each other's posts. Your response in #6 wasn't to the original poster. It was to Tom Wesenberg, and also made reference to Brent and myself. I just posted my experience.

I also noticed that you think you answered the original poster's question of milling a head"new out of the box" but he actually asked about heads that have been through hot cycles needing milling and if he should preheat his head a few times and then mill it to prevent the future warping that is associated with hot used heads.

I feel I did not miss the point at all showing pictures of my hot used head and the amount of milling I had to do. The original poster states that he appreciates us sharing our insights and experiences.

I did not put those steam holes in my head either. This head was on my car when I bought it. The head is also not low where the steam holes are. That area didn't warp.

We all thank you for your input and sharing your knowledge. It is ok for multiple sources to share their personal experiences and it is ok that other peoples personal experiences differ from yours. The average high temperature for the year in Southborough MA is 64 degrees and average low is 45 degrees. The average high temperature for the year where I am is 84 degrees and the minimum is 65 degrees. We all experience different lives.
