Yes, it is a passenger car engine (from engine serial number).
Yes, it came from the factory with hydraulic lifters (all 56-62 235 car engines had hydraulic lifters).
Yes, it has a 1958 block date code (shown above).
Does anyone have an interpretation for the head date-casting code?
CON 9 G14 (it looks like Duwen got that code from the correct location - check his photos).
Duwen, Jerry's advice is the best advice to be be certain that your engine still has hydraulic lifters. Check a lifter. You'll most likely have to replace the side cover gasket.
