Has anyone used the 1.6 to 1 roller rocker arms. Is this a worthwhile way to overcome the limitations of the stock cam in a LO3?

NJ SPEEDER has 1.6's w/ an LO3 and he's ran 14.30's w/ an autocross suspension set-up. So yes, they seem to improve the L03 "peanut" cam.

Magnums are not roller rockers. They are Roller-Tipped rockers.

Also, not all TRUE roller rockers will fit centerbolt valve cover heads because they will hit the valve cover mounting bolt tubes... Crane makes some Gold's for centerbolts but they are like $350...

 

Don't forget, as well, that they need to be of the self aligning variety.
