Tuning company?
 

Hi all, anyone here work for a tuning company/engine builder who would know what material would be used for inlet/exhaust valves for high performance engines? thanks jamie

I am not a tuner company nor work for one...


BUT
Inconel valves sodium filled? for exhaust valves anyway. I think.
Inconel inlet valves.

Hardened valve seats on valve to suit 3 angle hardened ( forgot material, but think it was 2 metal ) valve seat inserts in head.



Have a look at what GGR or RCM sell for valves...


but what do I know ;-)

Generally, Inconel for exhaust valves, stainless inlets. Some use Nimonic with sodium filling.

brilliant thank you! sorry i hadnt mean to sound like just engine builders but they were just the first people that came into my head! Will have a look into some those details! thank you
