Well I started removing my ac and smog today on my 85 z28 w/serpentine. I removed the passenger side bracket with the smog pump and ac compressor. I removed the high and low pressure lines, condensor, and accumulator. I removed the air diverter and line running to the cat.

Questions:

Where do the air lines running from the exhaust manifolds around the rear of the heads attach?

When you remove those lines do you have to plug any holes?

Whats envolved in removing the evaporator?

Also I noticed that my fuel pressure regulator has an allen head screw in the center, does this mean that it is an aftermarket adjustable one?

Please help me out, Thanks.
