buick riviera 1967 GS. I removed head to replace a stuck intake valve (old one looked a bit bent not sure how that happend). But when I took off the springs all the valves had valve seals. New head kit only has seals for intake. Should I get seals for the Exhaust valves? and if so what type of seal? same as the intake seals (rubber ones with two rings on them). Also the head is not from a 1967 its a 1969 based on my reseach.

Please help.
