I have the common 4.7L manifold leak/tick. I dont want to replace the manifold bolts with the garbage stock ones. What bolts can i used that will maintain the stock heat sheilds and will last long? Any links to stainless steel bolts?

Damn that is pretty young. I dont really now what to look for but my 05 4.7 with 60k seems to be ok. No ticking and i dont hear a leak, my old xj had a cracked exh manifold (like all 4.0's) If this happens to mine though i am just gonna get headers done.

I had an exhaust leak on the driver side manifold too. One of the bolt heads had broken off so I had to remove all the wiring out of the way from the top side in the engine bay for better access and I also removed the plastic in the fender well to give me access to the lower rear bolts. I then removed all the bolts and then the exhaust manifold. This left the broken bolt still in the engine. Just got some pliers and unscrewed it and replaced it with a grade 8.8 bolt. Messed up thing is that the bolt head ended up breaking again and it was the one I had replaced. I ended up using Grade 10.8 bolts and everything is still fine. Was able to put the heat shield back on with some of the stock bolts. Some had broke so I wasn't able to mount it exactly like stock. Sorry but don't remember the sizes. :( If you plan on doing it yourself, once you get one of the bolts out, take it to the parts store and size it. That's what I had to do. :)
