65 Barracuda 318 Rebuild, Cam, timing, lifters maybe a kit?

The only dyno I have is the Desktop Dyno. I built a basiclly stock 318 with 10/1 compression and then changed the chamber shape from "wedge open" to "wedge closed". The closed chamber head made 3 more HP and 3 more lb/ft at the same rpm. Who really knows unless you would build a engine both ways with the same compression. I'm sure the closed chamber heads do shroud the valves and don't flow as much but the combustion efficiency of the closed chambers may be as or more important. Pure speculation on my part.
