Titanium is a real advantage when you get into large 2.350+ and long valves with high rpm. If you plan on running them in a boat should be Crn coated and they will live a good life. Camshafts I originally had would tare the intake lobes up from the heavy valves. 2.4 intake. Large lifters and 55MM cam core would also help heavy valves.

They use titanium valves with light retainers and beehive springs in the higher rpm GM engines. Supposed to tolerate more rpms with softer progressive rate springs due to the lighter valve train.

Talked to the machine shop today, stainless intake valves $250 and heads done today, titanium $1100 and out at least 5 days until the valves arrive. Machinist said there is little to no advantage in running titanium given the springs it was running (and they will work with the stainless valves). So, stainless it is and it may be back together for the weekend.
Thanks for the input
