I just had a BAD head probem which ruined my LH head and front piston on my 04 FX4, 5.4 3v and before I just buy a stock replacement head, I might take the plunge for ported heads, DEPENDING on cost and how much they will improve performance.. I will also be finishing the install of my Powerdyne kit.... Any info would be GREATLY appreciated. I have done a ton of research on the net looking for 5.4 heads, but came up with nothing.....
