Victor jr heads

I've got a chance to buy a set of victor Jr heads that have been ported by a local shop. How do these heads compare to say a frpp scj head? These use a standard valve layout piston right? What about rocker girdles? Do they use a special set of a standard set

I like them , depends on your use though I guess and power goals SCJ would be a step up

Edelbrocks use standard valve arrangement and girdle
