what all interchanges between the iron and al heads
 

i just tore down my lt1 in my 94 camaro z28 and found out it had a iron head motor in it and i am tring to swap it over to aluminum heads i got the heads but don't have rocker arms or push rods does anyone know if they interchange? i am pretty sure the rocker arms do cause i have looked them up and the part numbers are the same on both types but can't even find anything at all about the push rods
