Topic: 21 stud heads

cliftford	-- 06-03-2014 @ 7:14 AM
	I came across a pair of 21 stud heads, part# 77E 6050A that have 18mm spark plug holes, I was told they came from a closed down dealership. They have the firing order and the cylinder numbering cast into them. I was told that they used for 1 year,1938. Can someone verify this? How rare are they? They appear to have never been on an engine

	Info I have only shows [ 77- ] - not [ 77E- ] and shows as cast iron 1937 commercial . I am not the best choice to answer this though as I only focus on 33-34 stuff . Hopefully some here that do focus on this year stuff will chime in .

	they are center discharge, correct? If so, they can utilize the newer block mounted water pumps which push the water, rather pull.

	I think that these are for a British V8 Pilot that was manufactured 1947-51 but had the 21 stud engine with 18mm spark plugs and the firing order on the heads. The part number in the 1949 parts book for Pilot cylinder heads is 77E-6050-C. Question is how did they turn up in the USA?

	The water outlets are in the center. Both heads have the same# and the word "front" cast in. so both appear to be for the left side. I live in WA state, could they have come out of Canada? Anyway, thanks for all the info.

	'37 commercial. Value? I have tried to unload NOS sets for the cost of shipping with no success.

	I have "77" heads on my car: Left head is 77-6050A Right head is 77E-6050 (with firing order and cylinder diagram cast onto head) According to my Ford book, these heads were used after February 1937, replacing the aluminum issue. Maybe also a service replacement for the aluminum heads. . . . 78-73B
