You cant check end play until you install the thrust plate and cam sprocket.
The end play is the just the difference between the shoulder of the sprocket and the thrust plate. I believe ford calls for between .002 and .009 You will have greater end play if the thrust plate is worn down to much. You can check the wear on the thrust plate with a mic.
For example .020 of wear would give you an end play reading of some where between .022 and .029. That would require a new thrust plate.
You need a little end play so that the cam is not drawn to tight against the thrust plate.

I run a torrington bearing on mine, so there is almost no clearance (bearing takes the place of the oil). The only way to measure is to use a dial indicator set up with the thrust plate and sprocket in place.

I always use blue on the thrust plate bolts and red on the cam sprocket. You sure do not want the cam sprocket bolt coming loose and the cam going deeper into the block , youll tear up cam lobes and lifters quick.
Ive seen it happen.

guys,
new cam is in the block. wasnt too bad. i ended up putting the sprocket on the end for leverage.
two new questions:
regarding the red loctite,the package says to remove it later down the road, heat needs to be applied. is that really necessary, or are they just telling us to apply heat to make it easier? my sprocket bolt didnt have any type of locking product on the threads when i took it out.
my thrust plate bolts had some type of locking product on the threads. it appears to be a dark red. could the people that did the work last time have used red? the package for red says red is for large bolts. would i run into problems if i use red on the thrust plate bolts? depending on the answer to the first question above, i wouldnt want to need to apply heat to the thrust plate bolts in order to get them off at some point in the future.
i know you guys said you use the blue on the thrust plate bolts, but i am just curious. i have red and blue handy, and if red is stronger and wont require heat later, i dont know why i wouldnt just use red for both the thrust plate and sprocket bolts.
thanks
