Default Engine Studs

I'm in the middle of putting new headers on and have run into a problem. The new stubs for the headers don't seem to tighten real well. They don't have a head to use so hand tightening is really all i've got. Am i missing something??

The studs should have 2 sides: one that tapers on the end and is a little longer, then a small unthreaded gap, then a shorter blunt threaded side. You screw the shorter side into the block until you get to the unthreaded part. Then you just screw the nuts onto them when you install the headers. IIRC, you basically just screw them in until it starts to get difficult and then stop. You don't want to try and tighten them too much cause you could damage the threading in the block. The old ones shouldn't have been in there too tight either.

I couldn't budge any of the nuts when I was doing my headers. I soaked them all with PB Blaster and kept working on them slowly until I got them free. I actually removed all 6 studs from the block... I only got the nut free from the flange, not the stud. So all 6 studs came rigtht out for me once I broke the rust.

If you cannot get the nut free from 2 of the studs, I would try BP Blaster (any auto supply place should have it) and slowly work on turning them until they break free. If you just cannot get the studs out of the engine block, I'm not sure. You could probably back 2 nuts against one another and use an open ended wrench to turn it out, maybe using some PB Blaster to assist. But if the threads are in okay shape on those, you can just reuse them.
Good luck.

Sorry I don't have anything constructive to add, but while we're on the subject... Does anyone have the part # for the header bolts/nuts? I'd probably like to replace mine when I do my headers in a couple weeks as they are probably all rusted to hell. And any other tips for a successful header job? thanks

....I think I do. give me a few.

[edit]

Crap! I just had two header bolts replaced at my dealer but it seems they didn't charge me for them so I don't have a part number.



............. wait that's a good thing isn't it?

BTW...I know for sure they are roughly $5 a piece.

I looked back at my invoice from when I did this... it looks like they charged me for the 6 nuts but not the studs

So the P/N for the nuts is 902370029

Just go to the dealership and ask for the header studs and nuts... they should know what you are looking for.

Got the old studs out and put the new ones in. Used the two nut trick, worked good. So i've got the new headers on (wicked awesome) but i've got another question. When i installed i tightened the nuts on the studs, then just cus its the way that i am, after driving around for a while and letting the car cool down i checked them. They we not real loose but i could tighten them, is this normal?
I thighted then and will check them again tomorrow.

Probably just your gaskets smooshing a little. No worries.

It's not a bad idea to check things to be on the safe side. Just make sure everything is torqued properly and you should be good to go. The magic number is 22.4 3.6 ft-lb for those nuts.
