push rod ?

problem with the rods is all my motors should have the same length and now im more confused because the 318 clearly has longer ones and it runs fine.

the ones in the 360 seem to be the same except the none oiling ones have a more pronounced ball on the end and seem to not ride in the rockers the same versus the non oiling ones and all pictures( i know prob general/generic pictures) at napa and rock auto show them being the ones with the more pronounced ball on the end
