VF29 will get you a safe 300/300, maybe 310 if you wring it's neck, which is not advisable as they throw turbine blades above 1.6BAR.
For 400BHP you dont need to touch the heads or cams.
Manley rods are up to the job, no point spending big money when you have a perfectly good rod available at a great price. Take a look at Mahle pistons, i prefer them to wiseco, at that power you could use the lower expansion material version, rather than the outright high power 2618 high expansion material, the low expansion material will be a quieter piston option.
Dont use an 11mm pump, it's overkill for this engine, all it will do is heat the oil up as more gets bypassed back to the sump via the Pressure regulator. A good condition 10mm pump is what you want, make sure you polish the pressure relief valve.
