Can someone explain the proccess for setting up them?
Are they adjusted outside the head?quote]

When you buy these lifters they just arrive put together and set to a "nothing setting"
You then have to one-by-one put it into the head, bolt the follower on and check the gap with a feeler on the dwell phase of the cam, you have to do this numerous amounts of times to get it right which means taking the follower out then back in then out again(into the same position)....you get the picture. The only way you can lock them up is to put the main body in a vice (wrapped in ally of course) and hold the central part of the follower while locking the locknut with another spanner. It is a very time consuming process (2hrs +) and is very annoying the tightening process increases the length of the follower also!!
Once they are all set, you need to run the engine for around 1000miles or so then do it all again, but this time it is easier as all you need to do is check the gap with a feeler guage, see what it is and work out how much you need to adjust it buy, once this is established, you need to take out the follower, measure it with a micrometer, make a note of the reading, then set the micrometer to what the follower length should be. Sounds complicated but its simple when you start to do it!

Eg Gap in engine = 0.35mm
Desired gap = 0.15mm
Set micrometer to the length of the follower then increase the micrometer reading by 0.20mm and adjust the follower until it just passes through the micrometer (use the old fashined g-clamp style one, not the vernier digital kind)

Simple!
