Chuck,

When valve is sticking open with "hockey puck" tight against the rocker and the rocker tight against heel of cam lobe the 1/4 inch gap will now be between the ball stud with correct height and the rocker arm.

I did measure the new and old ball studs and they're within .01 mm.

I did re-use "hockey puck", because I need to figure out what or why the valve is sticking open about a 1/4 inch.

I am able to see some of the valve through the spark plug hole when it should be closed and the valve spring height of the stuck valve is about a 1/4 inch shorter than other valve springs in closed position.

Thanks for your suggestions!

Justin
