Found a cheap 413bb, need info on it!

well, i found a super cheap 413 4barrel, and i was just wondering if all 413's came with max wedge style heads and is it pretty much the same as the 63 motors for all years, or what. i dont know much about the 413's, so some help would be greatly appreciated

thanks

No heads are most likely regular 2.07, 1.60 valves, closed chamber, nothing special. They all had 4 barrels. Made a ton of low end torque though. Also those olde ones had the different crank flange.
