a bit more engine porn for Pat. Was able to get a really good roller tip pattern with this set-up. The Comp Cams Ultra Pro Magnum rockers are really nice. For a few bucks more the peace of mind having steel instead of aluminum gives was worth it. Plus these use a ring to secure the fulcrum bearing as opposed to simply being pressed in like so many aluminum versions. On a street engine that will see a TON of miles these made a lot of sense.
