   I have new Speedmaster heads and my old Crane Cams 64790-1 T Gold Race Roller Rockers 1.5 are a little too short so I thought the 0.100" longer 1.6 ockers would work.
I need suggestions for good valued 1.6 roller rockers.  Im not sure about self aligning.

I like the PRW bushed stainless rockers & have used them on many engine builds .

Thanks, I will look into them. I sure liked my 1.5 Cranes, but not avail anymore.
Can you educate me on self aligning & offset? 
My Cranes have small offsets with L & R, but not the .650 offset I see for some, and they have springs on the shafts I presume to center them too

1.5 vs 1.6 is not a dimension of .100" " longer" but rather a ratio to allow more lift. If the roller tip is not centered on the valve then you need to adjust by shimming up the shaft or lowering it depending on which way you need to go.
