While you have the intake manifold off, beg borrow or steal a dial indicator+magnetic stand and measure the cam lift at the lifter.. If you tell me the lobe lift of 1 intake and 1 exhaust lobe I can tell you with good accuracy what cam is in it.
If you r+r'ed the intake without replacing the gaskets its very likely you have a manifold vacuum leak. That would explain 90% of your tuning troubles.
