440 source ductile adjustable rocker arms.

You need to call Mike at B3 racing engines and talk to him.

If the chicom copies 440 Source is selling are copied correctly you have a FAR better chance of the geometry being damn close or right on.

If you buy ANY OTHER ROCKER ARM WITH A ROLLER TIP the geometry will most likely be wrong.

So to save yourself all the nightmares of trying to fix something AFTER you buy the parts call Mike first and let him help you.

I haven’t talked to Mike in a while but I’m betting if he hasn’t used a 440 Source rocker he knows about them.

He’s your very best resource. I’d use it.
