Push Rod Length - does size matter?

[Big Daddy 70]

OK - so I had a noisy lifter last week. I took the valve cover off, and found one lifter pretty loose. I tightened it down till it stopped making noise, and plus 1/4 turn. Ran it for several days, no issues.

Monday it started to get noisy again. Pulled the cover off last night, found the same lifter loose. Removed the lifter, inspected the push rod, and found the top to be broken. I got the new one today, but it appears to be about 1/4 to 3/8 longer than the old one.

Will the length make a difference? There is plenty of stud available for adjustment up, so I am thinking it will not may not matter. I've never replacec one before, but it looks pretty straight forward.



Thanks!
