i got an extra set of heads to have milled for my 71 heads are stamped 73 and are off a 73 block but they to me look like the don't have the extra passages just making sure 1242556 casting also heads were short one retainer and 2 keepers anyone have any they would be willing to sell thx joe
no extras. if true 73 they exhaust port will have a 73 cast in them not stamped. but these should still be decent to use.
