Default Header install tips and tricks??

Okay, my powder coated parts are suppose to be here today but UPS dropped the ball and I doubt I will see them until Monday

So, I might have time either tomorrow or sunday.. I am thinking of tackling the headers.. Brake booster it removed on the drivers side which may help.

I am looking for any/all tips and tricks to help..

the Z is sitting on a Kwiklift right now. if I dont have to remove the tires it might be better, but I will manage if that needs to be done

so open for any help

thanks

I know I shouldn't speak to this because my headers are still in my living room, in the box!

....but when I was doing my shocks & had the wheel well liner panels out I was marveling at how I could actually see the exhaust manifold flange and how many bolts the factory couldn't get in!

The dipstick tube bracket may not work in the OE configuration.
Watch the steering shaft clearance.
Extensions for the O2 sensors.
Wrap the clutch hyd line from heat, and wrap any electricial lines from the heat, my thinking is the heat shields are now gone??
yea, pretty feeble! That's all I've come up with except for fitting the rest of the exhaust system to the collectors but I think that has to be done one a case by case deal.

Here are a couple of web sites I found useful when installing my headers last summer:

http://www.bcvettes.org/

http://www.pnwzr1.net/PNWZR1.htm

I can't imagin removing the stock exhaust or installing headers without taking wheel well liner panels out.

Be sure to clean the head bolt holes out very well so the new header bolts turn in as easy as possible. I used Stage 8 header bolts:

However, I did not feel it was necessary to install the locking tabs that came with the bolts. Summit has listing for a set of 32 bolts specifically for ZR-1:

The small 12 point 8 mm head provided a little extra clearance in the harder to get at holes.

Which side is more of a PITA?

1 Down, 1 to go

Driver side is removed and Header is installed

I did not remove rear part of fender well, having the Brake Booster out helped a ton..

dont forget to coat your bolts with some sort of sealant or anti-seize,as
aluminum and stainless dont fare well together ,especially in harsh environment
