Lash caps after cam mod

[DesertRat]

If you look at Mr Albans pics he's doing the Can Swap correctly.

He's has the Cam Specs, he's using a Degree Wheel and Dial Indicator.

If you have never used this type of measuring equipment before and have change a Camshaft its a Roll-of-the-Dice when you have issues such as discussed here.

Hi desertRat,
I have used a company which entire business is camshafts. They even manufacture bespoke camshafts. Their camshaft/mods sits in almost every car in the National Street Car series. Several Pro rally drivers, brand dealers and other automotive professionals use them. They are anything but cheap, but they follow their customer to a satisfactory result no matter what. They know cams. That's why I am not too worried.
As per their instructions my next step is to measure "exchange height(?)" at TDC using my dial gauge, after assembly (still waiting for the pistons to arrive).
No roll-of-the-dice, but I am just an engineer without professional mechanic skills, so that considered I guess anything is.

I guess my concern is that a lash cap is a 1950 style thing. The lash caps will gradually wear a groove into the end of the valve stem, but it may not be an issue for you as you probably aren't going to do big mileage. If the cam is a regrind, then they must have done some serious stuff on it to lose that amount from the base circle. Is your bucket ok, in the picture it looks like pieces are breaking out of the inside???

Well, the caps certainly adds another piece to the transfer of force, so it is not ideal. But I guess I can inspect caps and stems at each valve adjustment.
The buckets are all identical and seems solid to me. They all have a "bump" of extra (wear?) material in the bottom centre, which is clearly visible at my picture. Besides that all surfaces are smooth and even without any visible sign of cracks or wear.
