For the aluminum SCJ heads ... the S4073's.

thanks

Would the comp 1830-16 ultra rockers be the same geometry as the s4073 Harland sharp rockers ? Would they be a step up in quality ?

They are a step UP in quality but, they are NOT the same geometry.

      would the geometry of the 1830-16 rockers work well with the scj a heads ?

I don't know ... they work OK on A460 heads but, I never tried using them on SCJ's.

ok, thanks

has anyone else used the 1830-16 comp rockers on the aluminum scj heads ?
