Hi
What is the headmarking for the cylinder head bolts on a 1966 427 390.
I can not find in Tec Manual.
Thanks Tony

They are a slightly indented head bolt with a prominent "cross" (+) in the center. The ends of the cross extend virtually all the way to the perimeter. The manufacturers id is seen in one quadrant of the "cross". A typical ID is "M" (Michigan Screw and Bolt). Other manufacturers may have supplied bolts, too.
