[DeTomaso] Bolt length

My ARP head studs have 1.2" of threads that screw in to the block.  They
screw in without bottoming out.  I didn't measure how deep the threads were.

So, the block has at least 1.2" of threads.  Of course, that doesn't mean
that stock bolts on stock heads would use all 1.2".

1/2-13 x 4-5/16 is the size and length of the 351C head bolts.

I have no idea how far they thread into the block.

As Jack would say... Good luck.
