ok thanks . it gets hard to follow along at times.
Anyway, to answer part of his question . T&D and Harland sharp have rockers that will fit the eddys, and if one were to rev them past 7k . I would run hollow stem ferrea intakes at the very least with manley tool steel retainers and manley nextek valves . for max effort apps, the heads need to be ported by someone that knows what they are doing.
if one is swapping the intakes out only and running their own springs, it is cheaper to buy the heads with the valves then just ebay the intakes.
in case the valve stem heights are fairly uneven between the intakes and exhaust, lash caps can be run on the shorter valve even with solid lifters.
