Well, it seems nobody else is going to mention a high compression head so I will.

A 5.5 Snyders head will most likely solve the hill climbing problem and crossing the bridge problem without changing the rear end ratio which would be an enormous cost compared with changing the head.

To answer the first rebuttal before it takes place,no it will not wipe out your babbit or cause other catastrophic damage unless your engine is on its last legs already. 5.5 compression is really not "high compression even in the time period of the Model A Ford
