Anyone using the 440 Source Hydraulic Roller Lifters?

Check to see if the oiling band on the lifter rises above the lifter bore at max lift on the cam lobe.
My cam is only like 540 lift with 1.6 ratio rockers force the valve open about 577. I put one of the lifters back in the bore on a cam lobe that was almost at it's max lift....the oil holes are below the top band and it looks to be okay?



top on motor already taken off....
