We have a limited supply of Ti valves. They are flat faced and coated.
Here are the weight differences for one valve:
+3 Intake
Steel- 58 grams
Ti- 41 grams
+2 Exhaust
Steel- 50 grams
Ti- 33 grams
The cost per valve is $175 for the intake side and $165 for the exhaust. We know they are expensive but they are hard to get.
