At 200 deg F that is a 130 deg F temperature increase, so a 3" stem would grow 6.33xE-6 x 3 x 130 = .0025"
But the head will also grow and it is usually aluminum; the coefficient of thermal expansion for aluminum is twice that of steel.

If the rocker arm pivot hole also enlarges, the pin it pivots on will too, making that a net zero.

Man, you opened a can of worms. I going to leave it for the engineers at the factory.

Yep, I just wanted to keep it simple to respond to Keith's observation on RX3 lash versus others he has experience with.
