Default Hooker Headers/Sidepipes: General and w/ Steeroids?

I have my car up inthe kwiklift and getting into my winter projects. One of them is replacing my current dual, rear exit exhaust with Hooker Sidepipes.

Any general issues, tips, etc with installing them on my 73? I read somewhere I might need to dimple the drivers side.

Any additional issues with the fitting the hooker headers/sidepipes in a car which also has the steeroids power steering conversion?

Thanks
Shane

Expect to "clearance" one of the tubes on th left side to clear the steering shaft. I had to on the 65. It's a bit more than a "dimple"

Do you have a pic? Which tube was it?
Thanks

I didn't have to dimple any pipes when I installed on my '76. Biggest problem for me was the passenger's side on with the A/C compressor. My only suggestion would be to make sure you get all the header bolts started before you start tighening them down. I also used allen head screws because I could not get enough grip on the stock bolts, especially for the A/C mounting bracket. Use high temp loctite to keep the bolts from backing out.

Do you also have steeroids installed?

Man it's ugly down there. Someone needs to do some refurbishing!

Anyway. It's pretty hard to see but here is what I took. I will also tell you I was having binding problems with the column when I first installed the kit. I had to take as much angle out of all the joints I could. I actually cut the steering shaft about an inch to reduce the angles on the joints.

Thanks a lot. That is really helpful. So is it just that first tube way down at that bend? Any tips to making the dent without opening a hole in the header?

I used a large diameter impact socket maybe 1 1/4" and put it on a long extension. I used the extension as a handle, set the socket on the pipe where I wanted the clearance and hit the socket on the side with a hammer. It took a few trys but ultimately it left a nice curved shape without a kink or crack. I can't remember if I heated it with a propane torch or not. Seems like I did but I really can't remember. It's been a while and I have lousy memory. Expect to damage the finish and be pleasantly surprised if you don't. I did this with the headers and rack in the car. Obviously I took the steering shaft out.

Sky65 is correct. You will have to dimple the drivers side #1 header tube to make clearance for the steering shaft. You PM'ed a buddy of mine (SLVR76) about his install. We did that job at my house and it more aggravating than hard. We had to mock everything up and pull it all back out a couple of times to make the dimple since we didn't want to just bash it in. You will have to use a torch and get it cherry red (his headers were stainless). I like the idea of using a socket to make a smooth dent, but we used a ball peen hammer. Once we were done, you can not see the dimple unless you know it's there.

We had to udjust the u-joints over and over and over again to get all the binding out. You'll damage the rack if it's binding too much.

Also, you will not be able to install the headers on a Kwik Lift unless you also put the car on jack stands. You have to angle the headers way down to get them up in there. This is how high we had his car off the ground:

Thanks for all of the tips....I have had to jack the car up before while on the kwiklift so should be ok. It only makes me nervous when I have the entire car on jackstands on the kwiklift. ;-)

Here is what I know about installing (in a `76). No need to lift the whole car, only the front end. Hooker says 36 inches off the ground. I was at about 30 I'd guess. You need plenty of clearance to be able to rotate the header almost vertical to be able to install. If you are not hgh enough, the collector tubes will hit whatever is underneath as you attempt to install. Once you get the car high enough, they should go in quite easily.

Re bolts: Yes, start all before tightening. Yes, spring for the ones with allen socket heads. Additionally a wrench (7/16) heated with a torch and bent into a 90* angle with a slight twist in it is well worth your time to fabricate. I did not use loctite, I used teflon gel to prevent galling from stel bolts into my aluminum heads. Intrestingly enough, I saw some allen head bolts at um....Autozone I think, that had safety wire holes in them if you are worried about them backing out. I think they were made by Spectre. If mine back out I will go this route. I am not putting steel bolts into aluminum heads without tef-gel.

Also be sure to use anti-seize where pipes go onto collectors if you want to have any chance at all of removing them later.

I did the same with my 79. No problems at all, I put them on my self took most of the day. HUGE DIFFERENCE in performance vs. the reg Hooker hedders 2.5" true duel exhaust twin high flo cats.
This was with the built 355 Dart Alloy Head small block. I was probabally chocking it with the other system.
