Default Re: New block

I CMMed a pair of new Victor head gaskets as a rough way to get the bolt patterns for 21 and 24 stud heads. The red circles are 24 stud and the blue circles are 21 stud. It looks like there are 12 holes that are the same, the row across the top and the holes between the cylinders.
