Hi, i have them insalled on my 81 vette, motor modified, sounds awsome and not bad to install

Install is a little work. Do what Rick said but you will need to lift the front up a little to slide the headers in from the under side. You will loose the plug heat shield. Here is what I did to protect the plugs. suncountry2010-02-21 20:37:34

You'll need to cut the exhaust pipes and either clamp or weld on collectors to attach to the header flanges. Also buy high quality header gaskets.

I don't run Hookers so I can't say too much about their particular install. I did put my headers in using the same method Rick explained minus the plug removal.

I had to remove my wire looms though because the are aftermarket and are mounted to the valve covers. They stuck out too far and hindered my attemps to drop the drivers header in and to allow enough working room for my hands to start the header bolts.

As far as the sound.... if you don't have them now you are gonna like it. This vette was the 1st car I ever owned that I ran exhaust past the header mufflers out the back. I didn't think I would like it but I was wrong.

It gave it a great sound behind the car and a comfortable talking level inside the car. Plus no more exhaust fumes inside the car. (Growing up sometimes ain't so bad....)

Mine are long tube. If you are attempting to gain performance then you should reconsider the choice. After all if you are installing headers it wont be stock so get everything you can from your choice.

Another point I think is a must is to choose ceramic coated headers. They look a ton better, are more maintenace free (no occasional painting required) and they outlast traditional headers.

If your torn between staying original and headers then stay original at the motor and shoose a turbo style muffler that will provide you with a more distinct throaty sound and can easily be changed back to OEM within a small amount of time.

Here is a LINK where we previously discussed headers. You may want to PM Gunslinger.... he has block huggers and really likes them. Bruce will be able to give you the pros and cons.
