Ok so ive recently installed some moose new racing valves the intake valves are fine, but the exhaust valves dont seem to sit right.
They are a little larger and when placed in they sit higher with out a shim in they still sit high.
Does anyone have any advice?

My advice is to return the cheap stuff and use genuine Yamaha valves.
