The most interesting thing about 1960 heads is that the fins are widely
spaced and perpendicular to one another. These fins are also shorter and
have less total area available for heat exchange. Unlike later heads, the
castings have much less flash and are not in need of the deflashing but they
are "rough" and scaly to the touch. If these heads were not made so well, I
would not comment on it but the NOS 60 and 61 heads have the best quality of
finish and machine work. I imagine if Tony's experience is any guide, the 60
engines probably are subject to overheating if taxed because of the smaller
surface area than later head designs. I really like that flapper valve
instead of exhaust doors!
