I have a 66 250 block sitting around and was considering rebuilding it. I disassembled the head and found that the valve seats and ports were rusted from sitting in the weather for the last 20 years. Would it be cheaper to clean it up and remill the valve seats myself since I have access to a milling machine or to just go and buy a new one? Also, is it possible to put small-block chevy roller rockers and roller lifters in this thing or are there companies that make performance parts specifically for inline sixes? Thanks, Drew
