I'm assuming you have no emissions testing to go through.
Not having a computer to have to re-tune will make things much easier for you and keep the low budget intact.
I would run the vortec heads, air gap intake and a carburetor if you really want 400 to 450 hp. You will spend a bunch of money trying to make a TBI system function at that power level.
Have the vortec heads machined for retainer clearance at .550" lift.
With ported vortec heads the LT4 hot cam, 1.6 roller rockers and some Comp beehive springs will get you to the 400 hp level at the crank.
