The original BOSS 302 Cleveland heads are no comparison to the modern CHI heads used in the Engine Masters challenge. The new CHI heads come in a wide variety of port sizes, combustion chamber volume, flow characteristics etc. CHI have much better lower rpm flow chararteristics than the standard Cleveland head. Engine Masters measures h.p. from a low rpm range up, the original C heads didn't even 'wake up' until 4000 rpm. Cam profile would also be a huge factor in the Engine Masters challenge (as well as quench). Todays modern cam options and a much better understanding of quench makes for a CHI design head totally unlike what was available in 1969.
Myth Busting? Maybe, with some qualifications required.
