Pushrod to Roller Rocker geometry?

[B3RE]

Thank you. I started doing some looking at mine..it looks like it has lazy outward lift at the start of lift fulcrum. Now I see why the rockers need to be custom.. a bit shorter as the rocker gets higher.. correct?View attachment 1200484View attachment 1200485

That rocker motion across the valve tip is really bad. The MW heads I have in the shop have a step in the valve stem where the guide was digging in at full lift, due to the side loading from rocker sweep. They were using the same stock stands that you have.

I have the B3 set up on my 440 source heads with T&D offset rockers. they had to be moved a LOT for my .610 lift
