Speedmaster heads for SBM

Saw these on ebay. They are aluminum LA copies with magnum runners, and combustion chambers. Just type in mopar 318 aluminum head.

The EQ heads are total magnum copies in cast iron. Avail with either magnum intake bolt pattern, or LA series pattern.

The EQ heads are either CH318A or CH318B part number

The reason i am asking is these are $313 each as bare machined castings. Might be a good deal for a budget builder if the quality isnt crap.

I would bet on Pro Comp castings,almost guarantee it. They copied the Edelbrock head, LA style. I've owned a set of Edelbrock LA heads.And currently running a set of E.Q.'s,on a Magnum.Looked at a set of Magnum Edelbrock heads online,chamber is completely different.. Somethings wrong.....
