CA Valve Spring Specs

Appears that the tool cant accommodate the wide rocker pushrod to valve spacing. Ive enquired to the manufacturer if additional spacer inserts are available. Unfortunately, i think that will make the readings worse not better...lever arm pivet point is presently behind the valve which means it requires more force to compress the spring

I believe ive found a significant issue with cylinder 3 exhaust rocker. When you remove slack and aren't careful about applying a light side force, it twists slightly. Then if you measure it, its in spec. However if you are careful to remove slack by applying perfectly in line force, it only has .003 clearance. Not good. Ive reset the clearance for the inline movement and will see how it runs. Unfortunately, i left the key on and ran the battery down and its taking forever to charge. Several rockers are similarly worn. I had assumed the rebuild checked all that but apparently not. Im probably going to buy a complete new set if this helps. With so much wear, when the push tube contacts it, the rocker again twists.

here is a picture of one HEAD that had a bad freeze plug.... look at the two valves and their rockers and you can see they are OFF CENTER.... That seems to be very common on these old engines..
