463 had the L4-134. 473 (1950-51) and 475 (1952 on) had the F4-134.
 
Is it a flathead, which would show you 15 nuts holding down a flat solid chunk of iron across the top of the engine about one and a half inches thick (That's an L head); or does it have a sheet metal rocker cover sticking up on top, not flat (that's an F-head).
