07 f150 5.4 3v cylinder head question
07 f150 5.4 3v cylinder head question I'm in the process of rebuilding a 07 5.4 block is almost done but machine shop called and said both cylinder heads are bad and need replaced I was wondering what the difference is in 08 and up heads is it just the spark plugs thanks
