Tom please give me access to the "iron pile"! That is a 1bbl head. If it is a 76 the wide valve cover is required. I would love to be able to take one of those 1bbl heads and see if I can machine it to take a 2bbl carb like has been done with the small Ford six. The only 1bbl head I currently have is on the car but just looking from the top it would be a job. Jay
