Anyone using Smith Bros. 440 adjustable pushrods?

  After farting around trying to find Crane ductile iron adjustable rockers in 1.5 ratio for too long, (They are and have been out of production for some time now.) I thinking of going with Smith Brothers adjustable pushrods for my 440. I have a few lifters clopping (Mostly till warmed up well.) and know it's due to rebuild tolerances stacking up on me. As I may change heads or do other things I don't want to use cut to fit pushrods only to chuck them and redo later. The plan was always to have an adjustable valvetrain but the whole adjustable rocker thing is overkill and too costly without the Cranes.

the lifter with the valves open bleed down while parked & with take a few seconds to pump back up .
I have been using the stainless PRW rocker arms available in 1.5 or .16 ratio
