Throttle body & Intake Issues

[ACTI0NMAN-1]

as stated above p72 heads wont take any other intake manifold.

unless aftermarket.

I recommended you change the vtec cross over point to slightly higher if converting your IM.

Yes i agree, the standard crossover point is a little low, again all to do with torque curve, personally i raise it to about 5000-5400 with vafc or field or similar even if running standard manifold
