360 for a day

yes on the bigger spark plugs!no temp gauge in bung holes, standard spot on intake, has horseshoe gap.bottom side of head has no numbers, just a stylized I and C,emblem. rough measurement says valves are 1.78/1.50, 318 size. its definitely a 360. cleanest used motor ive ever taken apart, no bore ridge whatsoever and still has crosshatching
