Re: OK, Stocker "valve jobs".
Success!!
Between the +.050 locks and some moly retainers plus some shims i found from 30 years ago, i got it!
Break in pressure is 50 on the seat and 150 over the nose on all + or - 5#
Running pressure will be 110-120 on the seat and 265-270 over the nose
Once that was done i rechecked all the stem heights and found a couple too tall so i trimmed them about .020 on the 4-5 i had to adjust.
Next up was a way to check the springs on the head? cant find my checker so i made one that fits the rocker arm and a 1/4? drive torque wrench. By taking the springs on and off to confirm, i found 50? # is equal to 50? # on the spring. 90? is 90? etc.
Now i can confirm spring pressure on the car.
Another benefit to the tool is, i bolted the rocker arms down, then used the tool to compress the springs .400 or so and after using market on the tips i was able to (crudely) approximate where the rocker and spring contact. Almost all are a thin line on the stem but some are a little towards the outside which means the rocker arm is too high (or you have too long of a pushrod)
Obviously its not perfect, might of pulled too far or not far enough which would affect where it marks but generally it was pretty good.
Pulled the intake and heads off the car and now have to pull the front of the engine off to change the cam.
Getting closer!
