torque these bolts.. you're kidding right?

[ShiftTheDrift]

I'm trying to put a set of JBA headers on the Cobra and the instructions say to torque to 23ft/lbs.

bulls#$t. So far, I'm only able to get a socket around one bolt.

How is one supposed to do this?

I have three sizes of bolt heads and I can't get a socket on any of them.

Thanks!

I went through the same thing when i installed my headers. It was impossible to torque them suckers! I just tightened as much as i could and kept checking them every so often making sure they didn't back out. No leaks yet .

huh.. that sux!

Yeah, that is the same thing with my upper intake, trying to tighten the nuts at the back/front is impossible without grinding down a perfectly good socket. So I just tightened them until they were flush, then about 1/4 turn past that. That should equate to 25 ft.lbs.

grings down the outer edge of a closed end wrench

I didn't know they actually made a torque "WRENCH".......lol



j/k man

I think they were talking about in order to actually torque it to specs......

Yeah, only way would be to grind down a socket to fit.

Get some new header bolts while you are at it. Trust me, you don't want to go through the pain of installing/tightening those any more times than you have to.

I got some Breslin 1" locking bolts, and no issues since.

I used some allen head bolts from Lowes. I think they were grade 8 but I can't remember for sure. The allen heads were still a pain in the butt, but they were easier than using a socket or an open end wrench.

[95snoozer]

torque wrench > adapter > allen wrench

UPDATE: Late Evening

Okay, it turns out JBA has shipped me the 1 5/8" headers verses the 1 1/2". It wasn't until we grinded out a few holes for fitting on the Trick Flow heads when I noticed they just looked bigger?!? I went back and looked at the packing slip and the part number translates back to the 1 5/8" version. We got them on the car and there was one or two bolts that were a little stubborn going in, but no big deal.

My main concern is..

Why would they make 1 5/8" and 1 1/2" versions and more importantly, what affect is this going to have on the motor?

 

[95snoozer]

you should be shot for running a 1.5, the 1 5/8s will be ideal

You're a riot! Now, why is that?

It took some real shoehorning to get them in there.

With a 1.5" primary you arent going to have much more flow than the stock manifolds. Most aftermarket headers are 1 5/8" Some are 1.75 for ultimate flow.

 

[ShiftTheDrift]

Okay, that makes sense. They are noticeably bigger once they're in the car.

Do you think they might sound a little different?

Probably a lil...

Make sure your re-tighten the bolts in a day or two. You can get special thin wall socket or use a crows foot on the torque wrench. If you don't keep the bolts tight they will leak and you will have to replace the gasket. I use stage 8's on mine and they don't back out.

Gotcha.

..a tip of the hat to all those who shared advice. Thanks guys!

I know this thread is old ...... but in searching, this question came up.

I'm ordering those Breslin's. Will 0.75" work? Or do I have to get the 1" ones?
