Since you've got no responses by now I'd think the best bet is to find primary sources yourself. Local libraries most likely have microfilm copies of contemporary newspapers with sports page reporting. Schools themselves often keep archival copies of yearbooks, although reporting by student editors is suspect and track, being a spring sport, usually gets incomplete results. Alcalanes HS may have an alumni association or website which could possibly provide networking to former student athletes or coaches with personal knowledge. Also, have you tried contacting the CIF Section office to see if they have piles of stale records or publications sitting around in files somewhere?
