Apologize if I over generalized Jerry - We're on the same page. People many times used stock or shimmed springs and stock 1:5 rockers in the '60's to try and save a few bucks (against my better judgement even then!) and rev limiters were for "serious racers" and many of my friends were enlisted men living payday-to-payday.

I do believe that the modern heads and their associated valve train components are superior and a bit more forgiving.
