many times it is just as easy to just take the lifter out and look at lobe many times the lifter will be bowled out cam lobe will be shiney and nose will be round side to side and will have ramps ground off the fast way is look at a good lobe you should easly tell just looking down the lifter bore. if you do not have a 1 inch dail gauge to measure the travel of push rod . if lets say it a ex side lobe you think is bad you use a good ex lobe back off rocker arm. crank engine by hand. take out spark plug engine will be easser to turn. turn the engine till you on the base circle off cam now mark push rod with a fine tip sharpy marker by head make a line in the push rod . that can be copyed easly by guild plate wiil do .now crank till your at full lift mark push rod now you will have two marks on push rod and almost to very close to .332 now check the bad lifter side marking the push rod the same way as you did the good side back off rocker . check lifter at base circle and crank to max lift now mark push rod you will have two marks like test push rods . now take push rods out a look at your marks or you could messure them from the center line of mark to mark both should be about .332. now if the good push rod it lets say close to 300or 360 and bad lifter side is only 200 then you know it is cam time
