Rockers

[eric]

Hey everyone
I have been given about 6 boxes of parts.  in those boxes there are some rockers which i was told are higher ratio, but he doesnt remember what they are.   is there an easy way for me to tell? should i bring them to airspeed and have them tell me?  I looked on them briefly but didnt find anything that seems to be an identifying mark or anything.  
also, if i use these do i need shorter push rods? from what ive read and understand i do, but i though i'd better double check first

thanks again

so i continued to dig through my boxes, and deeper in the box where the rockers were, there was some brand new, shorter pushrods that matched the rockers very nicely, so i put those in
