W2 Rocker Arms - Can Econo rockers fit W2 race heads

[Rocket]

A friend of mine has a set of W2 econo rockers that I was hoping to use on my W2 race heads (milled pedestals). Does anyone know if the econo rockers can be used if I use the race W2 race shafts and stands?

Thanks

i think the w-2 race head uses a off set rocker shaft so you can use larger diameter valve springs, im not to familiar with the econo w-2 but i believe it uses a standard shaft, but the rocker arms themselves will interchange.
