If you are buying new and your willing to pay for the titanium now versus later you will be way ahead to spend the extra $1050 now. Also I would shop around. Lem, Charlie, and others sell/work on these. I included some others below.


8 titanium valves at $100 dollars and up a piece gets you to $800 so for the extra $200 I dont think you will be able to have the heads redone for the new valves plus if you wanted the 5/16" stem vs the 11/32" stem you will need new guides installed cost $ idk how much but i would say you could easily have $2000 extra putting titanium intake valves in after the thought. unless you could start with a bare cnc head to begin with and even then I doubt you could do it for less.

Part number TFS-5451T8T5-C03 has 5/16" stem titanium intake valves. And 85cc chambers

Part number TFS-5451T804-C04 has 87cc combustion chambers and stainless intake with 11/32" stems

TEA does a version and can add what ever you want

Again this is just an opinion.
Hope this helps
