Also note that the un-shouldered bolts should not have washers.

I found in the junk yard both "M" and "C" head marks. The 68 Impala had "CS" head marks. The shouldered fasteners holding the lifting hooks did not have washers per your note 69Z28freak. The other fasteners on the intake are washerless too, right?

That is correct. No washers used on any bolts on the intake. That is why the lift brackets have the shouldered, built in washers for extra lifting support.

So are the shouldered bolts used on the lift brackets longer to account for the added thickness of the brackets?

Yes the non shouldered is 1 1/8", and the shouldered fastener is 1 5/16"
