The question was posed by Tom Wiencek based upon input given to him by
myself,
Series 1 to late series 5 alloy heads used a similar if not the same
castings.
Different year heads have different sized valves, with the series V
heads having the largest valves.
The later style heads were fitted toward the end of production on the
series V engines, and were used on the later produced Chryslor UK
"Talbot" cars using the alloy head.
The earlier heads are easily distinguished by having pressed in tubes
around where the spark plugs are mounted.
The later heads have a different casting, which elliminates the need for
the often leaky
sparking plug tubes.
Also, it appears that the later heads do not have a casting date on them
as did the earlier heads.
All the heads have equally lousy combustion chambers, and all the series
V heads
"early and late" used the same size valves.
There are no performance advantage to the later head, but it is a tad
easier to keep clean, and the newer heads dont leak oil from around the
pressed in tubes because
they dont have them.
