To be honest, I'm not sure? As long as the AFR heads use the same spacing on the valves and rocker pedstals as stock (or most aftermarket cylinder heads) then the shaft rockers should work (if thats what the shaft rockers were designed for),

I have a set of 185 AFR heads setting on a 347 waiting to go in my 91 one of these days with a set of stud girdles I had originally bought when I was lookng to use a set of canfields, they bolted down on the AFRs just fine so I suspect this spacing is probably stock or at least the same as the canfields.

Ultimately my advice would be to contact Steeda and AFR to make sure.
