Read about that too, while I understand this is an easy solution, where in the hell am I going to find a shim for this motor that is discontinued, and what are the detriments to performance?
For $5.49 plus shipping you can try the head shims for an OS 1.08

If it fits, get several and adjust the compression as much as necessary.
If you get the compression ratio adjusted so the engine runs correctly on the fuel you like to run in your other engines, the performance should be fine.
It is possible to make head shims by cutting up an aluminum soft drink can. I'm not sure that I could make them but I have heard guys at the field talk about doing it in the past.
