Pushrod length Question

ok, so I'm rebuilding my 440 and decided to go with a solid flat tappet opposed to the hydraulic since I had to many lifter issues. I have a set of 9.250 pushrods from a previous project and figured I would see how one fits. At .22 lash I have about 2 threads showing on the bottom of the adjuster screw below the rocker arm? After some research I'm seeing people recommend anything from 0-2 threads. I would love to have closer to 0 but hate to spend 100 bucks on new pushrods for another .050.
Do you think I would be ok with 2? Thanks
