360 vs 383

I think simply because the B engine will always have a better head makes it is the winner- whether stock or stroked with all the aftermarket parts. Common B head uses 2.08 int and 1.74 exh. (I have omitted the early heads with 2.08/1.60 config as the bigger exh valve head is plentiful as it was made from 1967 to 1977- nice long span) Going aftermarket heads the B engine gets even more of an advantage with oversize Int and Exh valves where the LA -even in the aftermarket commonly stays with factory 2.02 int and 1.6 exh sizes. Add to that the LA head has the "Pushrod Pinch" on the intake side that even the aftermarket has to have due to design. (No W2s) The B engine head does not have the pushrod pinch compromise. Id love to have a version of either. A 408 LA or Magnum with a six pack would make me happy as would a 438 or bigger B engine with an iron dual quad intake or even an Offenhauser with 2 600 AFB carbs.
