Since you are asking for an opinion.........
Hands down. For a budget friendly upgrade, buy a whole salvage from a 2001+ Mustang, Crown Vic, Grand Marquis, or Town Car. A low mileage can be purchased for around $800. Even lower if willing to accept a higher mileage unit.
This is less than the cost of new PI heads and avoids major engine work (and the risk if this is your 1st rodeo). A motor swap on the Mustang is mostly straight forward and can be done with only hand tools, rented engine crane in your driveway.
