You ALWAYS match hydraulic lifters to the cam lobes they came off of too, not doing so is the bast way to destroy cam lobes there is.

Head off engine like in video is easiest way to adjust the buckets and NOT using the original springs which are too much trouble taking in and out over and over. You get like some racing valve checking springs which are light enough you can easily install by hand using no valve spring compressor at all but still stiff enough to hold a good clearance number and then you can sit down and just set and reset all day long until clearances are right. With the light springs you can even turn the cams by hand to make it even easier. Pick the thinnest tappet or bucket you have and then use it in all holes to get a clearance on all positions and then you have a base number to fairly quickly sort out the others with after you have measured all buckets with a micrometer, calipers have too much error. Watch wear patterns on the tops as well, you may find a pattern that looks like it goes with a certain cam lobe but these are so low in tension there is not much top wear on them. Before you set up take fine sandpaper like #400 or so and dust the bucket tops off with it sanding in a circle pattern to average the wear out a bit and it helps the bucket to break in better with a cam lobe it was not matched to before. Make SURE all sanding dust does not get into tappet bores! It will eat the bores up! When doing bucket setups the cam caps do not have to be fully torqued, only tight enough to snug up to where there is no looseness to mess with your numbers. The caps must be in the correct order and facing correctly by arrow.
