!!!HELP -ATC 90/110 Valves

[jdparsons1]

Does anybody know if the valves on a 90 head are the same as on a 110? Im using the head off a 110 on my 90 engine but i need to know if i should switch out the valves.

they are indeed the same valves according to partsfish. Both valves have these honda part numbers, these are taken off the 78 atc90 and the 79 atc110

intake: 14711-028-000
exhaust: 14721-028-790
