273 Pushrod length

Hello there, I have had some progress, but now I face out next problem.

I have comp cam CL20-221-3 with hydraulic lifters.
Original rods are little pit too long ( measured legth at the rod is 7.497")(without ball at the top) just rod length.
It seams that I dont have enough adjustemt on my rocker and lifter assembly.

I know that some of You have more experience and I need to know will Comp 7821-16 rods fit my needs. (lenght 7.389") cause I believe that the way how they (Comp) is introducing to measure correct lenght for the rods, don't fit for the Pushrod specs what they are giving.
