These Precision Machining valve guides feature a small shoulder to ensure precise location of the guide in the cylinder head. Shoulder does not interfere with the bottom collar and allows up-to .600 valve lift without machining the guide. To be even more accurate, Precision Machining made a difference between the measurements of the intake and exhaust valve guides.
