Romac Balancers

We ran a Romac SFI balancer on our Dakota 5.9 crate engine forever with no problems, I have the same one on my 408 that is 12 years old & it will be transferred to the 416 when I finish it.
Was that on a magnum engine? I have a PRW SFI one on my 2000 360 magnum engine and don't care for it much. Thinking about trying a different one
