Something to note about that motor:
"2-valve 4.6 L, 5.4 L, and 6.8 L engines found in many 1997-2008 Ford, Lincoln, and Mercury vehicles may have aluminum cylinder heads with threads for spark plugs that are stripped, missing, or otherwise insufficiently bored out. Ford acknowledges this issue in TSB 07-21-2 as well as earlier TSBs. Ford's TSB does not state that this issue is caused by owner neglect. Ford's only authorized repair procedure for out-of-warranty vehicles is to use the LOCK-N-STITCH aluminum insert and tool kit. For vehicles under the New Vehicle Limited Warranty, Ford will only cover the replacement of the entire cylinder head; however, the Ford recommended spark plug service interval extends beyond the duration of the New Vehicle Limited Warranty."
