LS1 339 Head Casting Number? I know of the 806, 853, 241 numbers. Does anyone have or seen a 339 casting number? What was it stock on? Thanks, Dan

I don't know what these heads are either but I have a set on my recently acquired LS1 junkyard motor. The engine came from a 2003 Corvette. The patina is consistent between heads and block so I don't suspect anything nefarious on the behalf of the junkyard.
Maybe the PO. Who knows.

339 and 806 both came on early (97 and 98) LS1 engines. Not sure how they flow even compared to the 241's let alone a 243? Do you know what year Corvette it came out of? I'd guess a 97 or 98.
