21 Stud block, stud location dimensions?
Hi Everyone. It came up in conversation recently... Does anyone have the x & y dimensions of the 21 stud block's, stud locations? Something like a parts drawing for a cylinder head should work. Simple, right?

Re: 21 Stud block, stud location dimensions?
they are the same (24 & 21) except for the bottom row. If you are looking for 'approximate', any of us could measure the bottom row for you.

As I understand it, the piston centers and reddish-blue studs in the image below are identical to the 24-stud. The fully-blue studs are different. Distances between studs could be calculated relative to the 24 stud dimensions and reference-scale to the image. Jack E/NJ

The Green Bible lists all the studs and their exact length. A head gasket would give you the spacing.

Re: 21 Stud block, stud location dimensions?
I too would be interested in length of studs and which position on a 21 stud block. I think there's a length difference in either aluminum or cast heads....?

Re: 21 Stud block, stud location dimensions?
If you can work with a DXF or Autocad file, PM me your email address and I'll send you some files. I asked here a couple times and no one had the data so I CMMed some 24 and 21 stud head gaskets and turned the data into digital files. Not the same as having genuine original Ford blueprints, but the holes are symmetrical and consistent and good enough to make parts from. The image Jack E/NJ posted is one I posted here.
