[QUOTE="Reptar, post: 327081, member: 1883"] Yeah guys, read the FRIGGIN POST before you reply up about how horrible the plugs snap off, etc. etc. These aren't 3V 5.4 heads, they're 6.2 heads, entirely different! Going way back, the 2v 5.4's only had 4 threads in the plug wells and was notorious for spitting plugs. 2003 Ford fixed the issue with the 2v 5.4 and went to 8 threads in the plug wells. When Ford went to the 3v 5.4, the 3v plug design was funky, and they were notirous for the plugs breaking off. Thats where the special tools come in to remove the siezed broken plugs. The 6.2 is a 2v engine, and has 2 plugs per cylinder. There shouldn't be any plug spitting issues like the 2v 5.4 had, nor any broken plug issues like the 3v 5.4 had. Personally unless you go s/c, keep the stock plugs. If you want to replace them before the 100k service interval, then just replace them with stockers. You're not going to gain anything from changing plugs if the stock heat range ones are still fine for your setup, other than a plug that possibly isn't as durable as a stock one. Ford puts in a quality plug to be able to get 100k life out of them. I do run Denso IT-24s in my 00 HD drag truck, but it's far from stock with 700 rwhp. If you have a N/A 6.2, keep the stock plugs. Stock plugs are iridium to be able to get that kind of life out of them. As for your buddy with the L, if he spent $6k on a brand new head, that shop saw him coming and going! Most spit plugs can be fit with a timesert, which a lot of shops will do for $800 on the high end. Swapping on new stock heads should have been $3k max including labor. For $6k he could have had a built shortblock and brand new stock heads with cams installed, or fully ported heads and big cams on a stock block (although the rods wouldnt last long lol). DETAILS! Those issues you're referring to are with the 3v 5.4. NOT a 6.2! [/QUOTE]
