Push Rod Length Difference Between 62&63

Why the huge difference in push rod length between the two years? The engines are basically identical. According to Steve Christ's book the 62 is 9.59 and the 63 is 9.77. Also, the tool to check the valve clearance (t58-6565-a-1) isn't available so how does one get enough leverege to bleed down the lifters to check the clearance. I am having issues, bent pushrod so I need to check them.

'62 and '63 FE's were not exactly identical. Ford revised the camshaft retainer, timing set, stc. in the '63. I don't know if the lifters were changed at that time but you'll notice a variety of tappets were used through the years. This could easily explain the difference in pushrod lengths. Also each of the OE pushrods was available in over and undersize lengths. I would suggest that you begin by verifying that all of your pushrods are the same length and straight. If only one pushrod is bent (you don't specify which one), I'd first check to see if the specific valve was sticking or if some other condition could have caused some sort of binding. The rocker shaft itself could be bent or broken for example. Cracks can form at the hole for the last rocker stand bolt and the end rocker can become cocked and bind. Note that these cracks can be hidden by the stand so they may not be detectable at first glance. These engines are nearly 50 years old now so almost anything could be possible.

Thanks for the reply. What should I use to bleed down the lifters? My pair of pliers doesn't have enough leverage. I just need to check the valve clearances to make sure my push rods are the right size.

What is meant by, "...check valve clearances."? Do you supect valves hitting pistons? Have the cylinder heads been milled or other wise modified? Have you checked the installed heights of the valves? They should be 2.110" to 2.140". If this engine was running normally prior to the push rod bending then it would lead me to think the failure was not caused by incorrect length. Is this a new build or has this engine been in service for awhile? I'm just tossing out possible scenerios because you don't offer much background info. Re. the lever/tool you refer to, It looks to me that a suitable lever could be fabricated with some angle iron and a u-bolt.
