Technical engineering drawings Buick Nailhead

Anybody have a set of prints for the front of the nailhead block , need to machine a front cover for a resto/one off without having to digitize the block

 

Can you use a stock one for the outside shape , and transfer punch the bolt holes

Thanx , but I need crank centerline and cam centerline along with bolt and dowel locations, just trying not to have to put a block on the mill and indicate the locations. With the numbers I can CAD draw what I need to make a whole lot quicker for the customer
