Exhaust manifold install assistance
I'm in the process of replacing the exhaust manifolds on my '92 T/A with a set of L98 manifolds. I got the old ones off and am getting ready to install the new(er) ones. I looked in the manual to get the proper torque values and noticed that the manual shows three different bolts/studs. On the driver side it has 2 #24, but on the passenger side it shows one #24. I have two of the Fel-pro ES 75111 bolt kits. The kit has two of the studs, and four bolts. The four bolts all look the same. The bolts that came off didn't look any different from each other. Additionally, #25 & 26 have different torque values as well (#26 is not applicable to me as it is only for the L03). Anybody know what the difference is? For reference here is the figure from the manual.

The passenger side has a stud for the A/C compressor support. Not sure if the others are bolts. Either way, I wouldn't worry about it too much. It's not like head bolts that need to be exact.

I figured out what it was talking about for the most part. There were some that required the stud, and others that didn't. The studs were used for the A/C bracket, alternator bracket, and the heat shields. The rest were the bolts.

There's a stud for the oil dipstick. That one might also hold a heat shield.
