Default Magnar rocker/arm kit

I saw a magnum rocker set/arm kit for my 95 in Eckers. It looked like an easier install than roller rockers. Ecklers is claiming 20 hp with it:rolleyes:. Anyone have any experience with them?

Thanks,
Jason

They are basically worthless.
A real roller rocker will make more power because of reduced friction at the fulcrum.Real roller rockers will reduce oil temperature 15 to20 degrees because of reduced friction.I wouldn't waste my time with fake roller rockers.
You can easily clearance your valve covers for them, and if you don't change ratio's,you don't have to change springs.

And you can buy the LT-4 springs pretty cheap. I would change them as well.

Will the LT-4 springs work on an L98 with true rollers?

I would use a 1.6 ratio roller rocker(narrow body) with LT4 springs.
LT4 springs are also 1.25 diameter,so they should fit fine in the spring pocket.
