Some of you guys need to change your terminology around. All the valves will slide-out initially, even if they seize in the guides 10 min after fire up.
Some people will put their finger over the guide and with the valve in the guide.. pull the valve out to see how much vacuum pulls on their fingertip .. or better yet pull it out .500 and wiggle it.
If you can see it move... '.0015-.002' intake it's good. Regardless you want the exhaust to wiggle a little bit more than the intake/aka have more clearance.
Also.. check for the guide being reamed.
Many times the lack of reaming the top after the guide is installed is what's tight.
Google this stuff, it's not hard .
If it hurts your head that much... pay someone else to handle it ..or find another hobby
