I'm fixing to order some OBX long tubes for my 2006 5.4 and I want to put locking fasteners on for the manifold bolts. Has anyone used and liked Stage 8, Percy, or ARP bolts for an application like this? Heard Stage 8's might be a pain/headache, don't know much about Percy, and am not finding a whole lot for ARP for this. I'm open to whatever works and fits. And I'm open to not using any locking fastener if I don't really need them

 

I'm now thinking of simply buying a new set of OEM studs and tightening them after a few drives. Only issue I can see with this would be if the long tubes will shake more than a stock manifold or something like that, which I don't see happening.

Can't justify the price of the Percy's and the Stage 8's look like a royal PITA. If my plan doesn't work, I'll lick my wounds and get the Percy's. If anyone sees a problem with this, feel free to tell me

 

I use Stage 8 and I didn't have any issues installing them. Once they are on there, that's it. Done. Been a couple of years now, and still no issues. I would recommend them to anyone. Much better than stock.Look at how many threads are out there with guys who have broken off those factory studs.

Just my opinion...

 

Thanks. My thoughts with the stock studs was that I live in Texas and the truck has been here its whole life, so they shouldn't be too rusted, and hopefully another set won't be either. But I see your point. So the little clips and washers (or like apparatus haha) on the Stage 8's weren't too fidgety for you? I think the 04-08s have a little less room to maneuver than the 97-03s
