for '67 326. Have a customer at work doing a reassembly of this and is looking for the type(stud/bolt)and locations of the head bolts..says he has one with a threaded hole in the center of one. Would the '68 350 be the same. Pics would be helpful...if '68 is the same I can snap a couple of pics of mine...not sure never had a 326, nor rebuilt one.
