Just a guess but I'm running 61 390 Hi-Po heads that Keith Craft ported/polished/installed early 427 valves in. They are on a 459 FE with a low riser 427 dual quad intake. I asked his dyno guy how much additional power it would make with a set of Edelbrock heads in his opinion. He speculated about 30 hp. My KC reworked steel heads may be a little ahead of your heads - don't know what you have had done to them.
