newb question on 243 heads???

i know i am going to catch crap about this, but i dont have time to search at the moment or i would, im sorry!!!

just wanting to know if all 243 heads (stock with no work) have the same valve sizes? i guess what im saying if someone says they have ls6 heads, or ls2 heads or corvette zo6 heads, and they are all 243 castings....will they all be the same, valve size and take a stock push rod of 7.4" on a 2002 ls1 engine????

thanks in advance!!!

The LS6 heads have longer valves to compensate for the smaller base circle of that cam.

They all had the same size, but some had sodium filled/hollow stem valves, as far as I know.
