I'm not sure what you mean by replacement heads, but there are several factory replacement heads accepted for this combo. If you are talking about the World Products heads, they are not accepted on any Stock engine.

Factory heads are 461 (original heads). The 462, 291, 186, 041, 414, 492 numbers listed are all factory "replacement" heads.
