(I'm going to have to send you my Edel. Heads one day....)
Brians post is what I often refur to and mostly in the highlighted bold. If your engine isn't really more than a mild hop up over stock, the Edel. heads are not really worth the money invested. While IMO, the head (Edelbrock) is a good head for street and light strip, the expense vs performance return on a mild mill is not what I would call a big bang for the buck.
In this area, I suggest ethier porting the OE head or going to a brand new head in which these days IMO, would be the Indy/RHS head. Alot depends on exactly what your doing, where you wanna go with it and what is allready done to the engine.
Looking at your basic build info, it is not much more than a stock set up with a few extra goodies on top. This type of build was very common in the old days on top of stock short blocks. Your cam timing and lift are still on the small side. Though it will for surely make good power, it is still a streetable 100% of the time combonation of parts.
To really take advantage of the Edelbrock head, (OOTB adv. flow rates at least) I would be looking at least another 10* of duration and .550 lift at a min. amount. (In which actual at the valve lift will be slightly less than .550.)
