Hello,

The Edelbrock heads are designed to work perfectly on the engine combination you are planning. The port sizing, valve sizing, and combustion chamber size is right on for a .030" 390. Edelbrock does make a single plane intake (Victor FE) but for your application and RPM range the Edelbrock Performer RPM is a much better choice. I think you will also be much happier with the Edelbrock's price, availablity, and quality. The stock block and crank are fine but I would invest in a set of aftermarket rods (Eagle, Scat, etc.) The price is so reasonable now that it almost isn't worth reconditioning the stock rods. Don't forget to do the oiling mods to the bottom end. With the correct cam and carb you should easily reach your horsepower goals.
HTH,
