Simplest Way To Shim An Rb26 Head

[SiR_RB]

My heads in getting some work done and I'm changing some parts

If your starting fresh and need all new shims, what's the quickest way to do so ?

I was thinking of putting the buckets in with no shims, measure lobe to bucket clearance then take away clearance needed and this would give you the shim thickness needed ? Would this work or must you put a shim under the bucket before measuring ?

Any other ways people have done it and care to share ?

Put all the old shims in. Measure the clearances. Do the maths. Order the new shims.

If perchance any/all of your old shims are too fat and you have zero clearance somewhere, then you need to use the thinnest shim, or perhaps some other even thinner shim to do the measurements, which kinda sucks if you have to put them cams in and out a number of times.

using one bucket as a reference (usually the one to correct clearance) use a depth micrometer to measure the depth. Then reshim to match the depth of this reference. This method only requires the cam to be fitted twice.
