Help with Part #'s A-65050-B , and A-66050-B ??

[RTPbee81]

Trying to identify these part #'s. I have receipts from when my A was first restored (came with the car) receipt is from Birdhaven Vintage Auto Supply, 11/26/1986, coffee ring has obliterated the desc. but not part #'s
Part # A-65050-B was $165 (closes I get is B-6505 engine valve kit)
Part # A-66050-B was $95 (B-6600 is oil rebuild kit, or Oil pump), I was told the engine was not rebuilt(not by the restorer who sadly passed), but these receipts lead me to believe it may have been.


Any help is appreciated,
