Did Ford redesign the heads to cure spitting spark plug problem?
Yes.

So a 04 Excursion 5.4 would NOT have the spark plug spitting problem?
Thanks!
Correct.

Apoc, you must be confusing the plug spitting issue with the manifold stud issue on the 6.8L V10's.

All of the Ford modular engines suffered from the plug spitting problem up thru the '02 MY.

Don't all of the modular motors share the same wonderful exhaust studs? Or did they realize that the 6.8 was the greatest motor ever produced and was nearly perfect so they had to introduce a intentional flaw just to temper it's greatness?

Dunno.

While the plug spitting problem was covered ad nauseam for many, many, MANY years on the Lightning forums I used to live at (before I got bit by the diesel bug and moved over here to FTE permanently), the exhaust manifold stud problem was never a common problem that afflicted the L's.

Maybe the Lightnings got something better as part of the blower upgrade?

In all my time in the mustang/f150 world I never heard of the spark plug issue and here I have only seen it in the 6.8 so I just assumed it was only them. You know what they say about when you assume, you make Stewart look good lol
