Well, I am not a Chemist but I think that if you get stainless bolts the alumium heads will make the corode

Most people think torquing is not important. Believe it or not I've seen a lot of engine problems because of the wrong torque. Keep in mind Exhaust Manifold nuts are 17 and the exhaust pipe to manifold nuts is 30. Good luck. Before installation though, thoroughly clean the mating surface with a scraper. Avoid leaks and corrode and your car shall thank you. Aluminum is not a strong piece of metal but believe it or not it can take on iron which is strong. Think of a short guy and a tall dude, they both get hurt really bad if they get into a fight but the short guy may end up in the hospital lol Just torque it and you won't have a problem. Ps: Don't use a air gun or any type of special guns. lol Do it by hand whenever you're dealing with an engine bolts.

What size bolts are they? I'm about to swap headers but the kit I got seems a little off for nut sizes. Would like to replace them with new SS also what grade are they?

I got the SS bolts a a place called Fastenal. http://www.fastenal.com/web/home.ex
They have worked fine so far. Used neverseize on them before I put them in. Re- torked about 100 miles after putting them on. MPG went down but HP seemed to increase some.

I want to do the swap sunday so I wont get them in time, Any idea what grade metal they are? Don't want something too soft.

304 stainless. Maybe try home depot or Lowes. They are metric.

JCON

I was thinking 304 nuts, headers are also 304. Do we have a good write up on doing the switch or should I take pictures as I do it? I didn't find one through the search

svastano

No write up as far as I know. They are a real PIA to put on! About 3/4 the way thru I asked "and why am I doing this????"

JCON

That's what I want to hear

I haven't checked on the car yet but do you know the nut size off the top of your head?

I made a thread about the eBay headers not too long ago and I ended up not getting them because of other reasons besides the product, looking forward to hearing some feedback from you to sway my decision.
