Re: How do I measure how much can be milled off 1951 288 head?

I would NOT mill more than .030" off the head. you will loose breathability in the crossover area. Are you milling because of pitting, flatness, or because you think you're going to get a significant increase in comp. ratio? If the latter, there will barely be a discernable difference. If you've got performance experience you might notice a difference/ Most will not. It was a good running engine as designed and with the fuel that was available. The flathead design has it's limitations.
