a couple k head questions...
1 . sorting thru my k heads i have.i noticed that they dont match my part book numbers...all 3 sets i have have the same numbers.186682-52 and 186684-52
the part book says 186682-54 and 186681-52 for the front and 186683-52 and 186685-54 for the rear .
the 186684-52 heads i have has a relief cut into the area for the valves and the 186682-52 does not...which valves do i run...book says exhaust valve is the same for all models except kk but the intake differs so which intake should i run with the 186682-52 and 186684-52 heads i have?i assume 18070-54 for 54-56? ill be useing stock 1k2k3k4k cam set.
the exhaust valves i have say hd made in usa and a 33 on bottem the intake say hd made in usa and are about 5.558 long...exhaust look a bit longer.5.570
the valves came out of a part motor i picked up that had one of the three sets of heads i have on it so i assume it was run that way before.
other question is 2 sets of the heads have part numbers raised and cast onto the surface of the heads with a E under them...the other set has the same numbers but is stamped into the head and has a 1 under it ...is that set a early set or?
any input will be great.
