This should help you out a bunch.

Sorry but today I don’t have time to type a in-depth reply back.

You don’t need 1.77” exh valves unless your planing on buzzing the motor over 5500 and with a what might be a hotter cam the you can live with on long drives.

Note that your cam pick lift wise may dictate what length valves you need.

Also be double sure that any valves you do get have chrome plated stems, as I have seen a few companies/ sellers cheaping out on this important detail.
