RHS INDY LAX heads, magnum heads, 302 heads -what are you talking about?
LA engines need modified (magnum) or over a thousand dollars to run RHS heads.
As I understand it, the edelbrock air gap intake has to be utilized work with front accessories with the magnum conversion (vice the Chinese air gap intake, or the magnum repop heads 318B? 318A?).
The 302 heads need porting enough $ to justify new heads.
