Head bolt pattern/spacing

Anyone have a diagram or photo of head bolt the pattern with spacing between the bolts? I’m making a TDC stop and forgot my head gasket…
Thx

The one I made I drilled two 5/8" holes 6 1/4" apart and it worked fine. Drilled a 5/16" hole and tapped it 3/8 x 16 for the stop bolt.

About 6.1 ctc this direction..

If your off a touch a rat tail file will make it right

for the stop bolt i welded a 1/2 nut to 1/4 thick band stock with a 1/2 hole in it

also rouned the face of the stop bolt

Make the head-bolt holes slotted (at least one of them) so the tool can be used on multiple brands of engines, or shifted side-to-side to avoid piston domes/dishes.

A spare 4-Bolt Main Cap works well.
