The main thing that the OP needs to do regardless of the valve length used is to replace his stock however many 10K thousand mile valves with new ones.

I’m absolutely planning on replacing the valves & looking at the Marley’s in the FS section to see if they’ll work for me, if not I’ll buy a set of Ferrea’s.

Yep, When the factory two piece intake valve heads breaks off and fall into the cylinder you don’t get left with much!
