Yours is the early 2LT correct? It's really only the 1990-1994 or so 2LTE and 2LT-II that had the major head problems that were updated with a new head revision. The 1990+ heads are totally different than your early 2LT head.
Your cylinder head is the early rocker cam style. The later cylinder heads (1990+ engines) are a shim over bucket design that cam drives directly. Like the 1HZ and 1HDT in fact.
If you go to ToyoDIY and pound that part number in, it shows belonging to the 2LT from about 1983 to 1989. Although, Toyota does seem to have a few versions for that early 2LT too. Seems yours is the latest version (the earlier ones were 11101-54060 and 11101-54061). So if there were improvements along the way for the early 2LT, yours would likely be the best one to have.
These early 2LT heads usually drop pre-cups or valve seats before cracking apparently. Although many of these motors have high kms on them now with no issues. They are known to not have the over heating problems of the 1990-1994 2LTE and 2LT-II. They are generally long lasting as long as they are taken care of.
