You'll need to use a 1.65 ratio rocker to compensate for the loss of lift when using the Chevy rockers. The PRW rockers that Hughes sells for the Magnum engines are the 1.65.
Magnum heads convert to sbc rockers?

Curious if the 1.65 SBC rocker gets the ratio back to the factory 1.6 rocker ratio?
Yes, it does. Hughes sells the 1.65 PRW stuff for the Magnum.

Take a look at this 318 engine masters build. Super stout little piece.
I bought it and stuck in in a 71 duster roller I bought
Ran chevy rocker gear on it
