Does anyone know the difference between the type R valves and the normal B16a ones? Are the diameters different or just the number of angles?
I heard some people use type R inlet valves and reuse the original inlet ones on the exhaust side, anyone done this?

 

Exhaust valves are the same.

ITR Intake valves are deshrouded for more flow and less weight, as well as
having a sharper seat angle.

Be sure if you are changing to ITR valves that you have a valve job done so
that they are able to make a good seal with the head.

 

Thanks a lot man
So the Type R and B16A exhaust valves are exactly the same? If someone was going to use B16 inlet valves as exhaust valves, there would have to be quite a bit of work done to it then?

 

The R valve seat are 45 degrees, B16 are 60'
