Thanks for your input guys. I have a couple more questions now..
-I need a new exhaust system in my throttle-body injected K5, what would be some good choices that will last longer than a year? i.e., 10 years would be nice.. I'm considering the edelbrock shorty headers with ti-tech coating and possibly A.I.R.? Would the ti-tech coating make it last through the winters?
I might get a muffler shop to make up a new exhaust system for me. I would think that the brackets for a bolt-on system would be more likely to rust than a nice, clean welded job. I'm also going to go back to single exit exhaust to save some money and go quieter. Any suggestions on mufflers and cats?
-I'm also considering getting some herculiner for the rockers and anywhere else that would be prone to rusting under the body. Here is an example of what I would do:
