Magnum heads convert to sbc rockers?

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.

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

Are you saying that the SBC Jomar girdles will work on the magnum heads, the rocker spacing is the same ???

No, I didn't say SBC Jomars work, have read and heard SBC rockers will work
I posted somewhere earlier that I had read that Older Oldsmobile pushrod guides had worked without mods
