I'm not the biggest fan of Dove castings. They are often crude, but I have always been able to make them work. Many of the quickest Super Stock cars in the country are still running Dove parts.

But I have broken exactly two Dove rocker arms over a twenty year period of use - including solid roller applications, and the 2004 Engine Masters Challenge entry at over .750 lift. Thats a pretty good record, and certainly not a part to steer clear of.

Stock rockers will be perfectly fine at .550 lift. I would recommend aftermarket end stands if you do not have the fatory split steel ones.
