i wouldnt know that answer... but i'll give you my answer lol


in my experience it's better to get a length checking pushrod and get the zero lash length and add 10 thou for preload -the less preload on a hydraulic lifter can give you more power under the curve provided they dont pump up too much

i dont like one size fits all pushrods because too many engines that i've assembled have (as usuall) machining tolerances that can make one pushrods height too much/too little for other positions for a "one size fits all" solution to work

but i'm kinda a perfectionist about my builds

try listing his mods besides the cam(which works well with stock pushrods)
why does he think he needs differnt ones

you have roller rockers, so yours will be differnt
no where in the description for the the cam does it require them and no one uses aftermarket ones with just that cam and nothing else.

unless he has a custom setup in the top of the valvetrain, stock pushrods are the best bet. Don't fix what ain't broken.
