Anyone need any magnum heads.

Those are going to be the readily available china cast iron magnum head. Not as good as the "old EQs" and there are designed to be a stock oem truck casting. They CAN be ported, and the valve job improved, and if they dont have bronze guides or liners, dont bother

This would be worth a phone call to ProMax for your answer. This company prides themselves on getting their heads as rough as possible and doing them in house. The aluminum set that I tested and did a post about had a beautiful valve job. I called and talked to him and had a nice conversation.
