2nd Gen W2 Heads

Might have to replace my old 810s I have on my 340. Don't know till I do some more tests. In the interest of being prepared my question is on 2nd Gen race W2s. Since I have old school Mopar aluminum rockers can the second gen can still use these rockers? Oil through the heads? Believe its the third gen that went to oil through pushrods and I'd have to find T&Ds or something similiar. Thanks!
