Hope so! Were not on my RV. But again it was a 1977 who knows what the hell they did! Lol. All I know is I went to the store to get the plugs and I got the standard 13/16 style plugs went back there they didn't fit so I pulled one of the little ones out took them back and had them matched up. I've got a good set of 452s, that have been ported out in the shop. A block of transmission crank some six pack rods I've been wanting to put that together for a minute. Like since 2010 I think....
