413 Max Wedge Engine engine block controversy continues......

V is code for 1964 build. 41 is code for 413..... would be 42 if a 426.
Did they make 516 heads in 63??? I was expecting pedestal stands and maybe 200 heads??
I guess 6 bolt covers would be right for a late 63 build?? Not Maxie anything there, sans maybe the block. Forging number on crank and rods may help too....maybe not LY rods in that one??
Interesting....
