I don't see your sig... What kind of truck/engine is it?
Anyways, you are in for a definite chore. I guess the passenger side is just a bear. Everyone who has done it says to take the extra 15 minutes and remove the passenger inner fender. Good luck! You would be a star if you did a tech write up for the guys here!

it is a 92 f-150 with a 302. i have heard that the passenger side is a pain.
any tips like spray penetrating spray a day or 2 before multiply times unscrewing the bolts when they are warm or not? anything would help since they are the originals at 160,000 miles

I have done a many exhaust manifolds on the Hummv built for military applications.. the best thing I found to do is to spray and then spray some more with a penetrating oil warm them up just a bit then break the bolts free by hand and then use my air tools to remove them from there...
I am getting ready to do the headers on my 95 F-150 302 and it looks as if the passenger side is going to be some what problem matic being that is where me air tube from the air pump is attacthed to the exhaust manifold bolts OEM dont know what I am going to do with them on the new set

I put a set on my 351 in August, and it actually wasn't that bad. Now, let me say, I had put them on when the engine was out, but I still had to pull the passengers side off to fix a small leak, so the bolts weren't settled. Also, I had removed the air pump and all its hoses while the engine was out. So if you can get all that junk out of the way, the manifold is fairly easy to get at. The bolts however can be fun. Use lots of penetrating fluid working them back and forth. You may even need to use heat to get them loose. The real difficulty in the bolts is the position you are in to get at them. They weren't that bad when I had the engine on a stand.
Mine are a bit different though, as the headers are designed for a early model Mustang, so I needed some exhaust work done, and needed to fab up an EGR mount on the passenger side header, I think I still saved over a new set of headers.
