A good manifold/throttle body setup
camshaft selction will go a long way.

Those manifolds inlets are 64.5mm and you have a 68mm throttle body see the problem. Also the chinesse cast manifolds like Blox use a very poor grade aluminum. This leaves very rough casting which means it needs to be blended/ported to make any real difference.
Take a look at an oem Honda manifold vs for example Blox and its easy to see why the casting has to be hand blended/ported to make any real power gains.
