Roller lifter question

If i replace my solid roller lifters with new ones will i need to check my pushrod length or change them. Im not sure what kind of lifters are in there now. Are they a standard length? Sorry for the newbie questions.

The cup ht. of lifters does change from one brand/part number to another. I'd check what you have 1st....the change [if any] may make it better or worse.
 
With a stud mounted rocker, pushrod lenght that is good to go, moving things .020" aint a big deal.

Thanks Lem for the detailed answer. Im gonna try to find out whats in there now.
