If you are already happy with the power of a stock motor then just replace is with another one. Less down time over rebuilding.

I would get a forged short block to handle a procharger, not a must but its in your best interest. You could get one in the 1500 range. You could get a forged rotating assembly for cheaper but labor at the machine shop would raise the price

Well I'm on a budget build lol I'm looking at bout max of 700
If your in no hurry you could take time and find an 03/04 cobra shortblock and put your heads on it and that would handle plenty of boost

A stock 4.6 will hold around 450 for a while, you could get a stock one and run it on 7 or 8 psi until you could afford forged internals
