Joe, I'm running a ZZ4 in my '63 Vette and I have actual parts sheets
for the engine. If you want original equipment head gaskets, they are
GM Part # 12557236. Just out of curiosity, why are you replacing the
head gaskets? Did you have the engine apart? Or did you actually blow a
head gasket? If you happen to buy these head gaskets, I'd appreciate it
if you posted a followup and let us know how much the gaskets cost.
