Stocker Cylinder Heads....

Thanks for the advice Billy. Sometimes I wonder if the engineers cared about airflow in the 1950s and 1960s on most engines. I guess the emissions and CAFE standards forced the auto makers to make them more efficient in the 1980s and later. I'm thinking the 273 4bbl combo looks more attractive, basically the same 302 head casting. The 308 head isn't legal on the 273 but is on a 318. Sort of odd, but the 340 intake is legal for the 273 4bbl and apparently so is the old Edelbrock LD4B intake. Maybe that got in via the 1966 D/Dart engine? Now I wish I had that LD4B I bought in 1975 and gave to a friend in the 1980s.
