    220's use standard rockers arms. 227's use the offset arms.

    I bought mine around 1992 and I used conventional rockers no problem.

    I have used quite a few sets of the 220 AFR heads and standard rockers worked fine. I guess if you know what your doing it makes a difference !!! Now the 227 235 and 245 those use offset rockers.
