1972 351 Cleveland pushrods?

is it the exaust that uses the longer pushrods or the intake? im thinking exaust,thats why im asking, dont want to get them mixed up.

oem (8.400" hyd. 8.500" Boss , CJ solid ?), they are the same lenght.
got longer valve on int. or exh.or BBC rockers then lenght changes

My old 351 c had the same lenght on intake and exhaust everythinng oem stuff and when i built it I ran comp cam roller rockers and I also ran the same lenght push rod on both

If you have pushrods in you 335 Series Ford engine that are noticeably different in length, something has been changed or something is wrong!

this motor was built, I got the car with the rockers and pushrods off cause he spun a rod last year racing it and when the car sits for a long time, the guy takes the arms off to releive the springs. It has a 653 lift roller set up in it with stud girdles big springs and T-retainers and locks. He shifted this this at 8800 rpms so its not stock. I have the motor all back together and noticed that it has 2 differetnt lenngth pushrods, thats why I was asking. Tried to contact the guy with no results. Going to figure out now if it has a longer valve on one or the other.

Do you have valve tips of different heights? Different brand or application rockers? Any thing noticeable as to why the different length of pushrods? Install the valve train for one valve and check the pattern on the valve tip after rotating the engine. Pattern OK ? Try the other length pushrod on the same valve. Does the pattern look better or worse? Do the same procedure on the opposite valve, (i.e; intake / exhaust).
