Question PRT seals sizes

For a T120R
Where does one obtain various thicknesses of push rod tube seals to obtain the correct crush? There only seems to be on size in a gasket set. Can this be trimmed down if needed?

The white ones, which the tubes sit on, come in two sizes.
Standard 70.4752
and thin 70.3547
There are also others for different (earlier) years.

Ensure the tubes are fully in to the head.
Fit the head (+ tubes) onto the engine.
The gap between the the head and gasket needs to be about .040".
If its a lot more than forty thou, because the head has been skimmed, you may need a thick gasket.
Tighten the head bolts in the correct sequence.

Thanks for the reply Caulky
I didn't know there were different sizes available. Going to stock up on a few.
