    Roy, I looked at Mortec, and couldn't find either, but there was a head listed as:


    3725306....56......265


    Could you have misread some of the numbers? Maybe somebody else will come up with these exact ones, though.

    Might want to look at the numbers again. I found a block, 3720991, on Mortec, showing it as a 55-57 265.

    Are the holes for the valve covers to mount straight across from each other, or are the ones on the top closer together than the bottom 2 ?

    I'll double check the casting numbers and valve cover bolt holes and let you know. I am pretty sure Jimmyjeep is on the right track on the block. It came to me in a bucket of bolts and the guy I got it from had a 56 chevy in the past.
