Gary,
I'm new to stock racing this year. Per the guide it only shows the D7OE-DA head. With that being said did you question why the D7OE-DC heads was not there? I see they just changed the casting on a head that is legal for my combination so was curious how that happens.

D7OE-DA – 1977-1979, 302, Windsor small-block, 1.78/1.45 valves, 69cc chamber
D7OE-DC – 1977-1978, 351, Windsor small-block, 1.78/1.45 valves, 69cc chamber
D7OE-DC – 1977-1979, 302, Windsor small-block, 1.78/1.45 valves, 69cc chamber
