1. The shims have a top and a beveled bottom side. They are installed with the beveled side down, did you install them correctly. There is an installation FAQ for PT Lifters and shims available at:
Installing PT Lifters
...is this the installation technique that you followed?
2. The OEM and the PT Lifters are hydraulic, they do not all function immediately and very often will take several seconds to more than a minute to fully charge and pump up...so you have to run the engine for a bit. There is also a check valve in the lifter and if the lifter was previously used, you must release the check valve to compress the lifter before installation. There is a youtube that describes the various methods to bleed your lifters:
3. Being hydraulic lifters also means that their working height is (somewhat) variable, they adjust to the proper length needed as long as that length is not outside it's pintle intended travel parameters.
4. There is a detailed installation video available on the FAQ mentioned above, or you can view it directly on YouTube at:
