Who knows factory cylinder heads ?

If you take the intake off again and measure the lift of each lifter off the edge of the lifter, you can get accurate comparisons..without measuring the hydraulic portion of the lifter compressing against the valve springs.
Thank you, but that’s not happening. Lol! It’s a lot of work to remove and replace an intake. Never realized how time consuming it is, until I did it for the first time last year.
