[QUOTE="cobracide, post: 9868354, member: 4644"] If you have the money to burn then go with the newest '03 revision heads. If not, the suggested spark plug inserts should help. Since you have already blown out a couple of plugs, I would be going with the new revision 9 thread '03 heads. A good 5 angle valve job is about all you need for the '03 heads. Since the engine is out, also consider some cams. Ford GT cams for a mild bump, Stage 3's will get you a bit more and a custom grind will bump it up even more. Budget in what you can, good luck!
