Header Install?

[NVMYRC51]

I was fortunate enough to get a set of Jeal Headers for my 1990. I am collecting all the minor parts I need to complete the install and I had some questions. 1. What cats are folks running? C7 takeoffs? 2. Stock header bolts or ARP lockers? 3. Any tips? I am will definitely check out Dynomites write up as well. Thanks.

No cats here.
I bought the Stage 8 bolts for my headers. The locking c-clips would not engage in the groove. Waste of money.

I purchased a set of C6Z06 cats. I got this off the C6 Corvetteforum Parts for sale. It took a while to get them.

doug rippie long tube headers ceramic coated, no cats dumping to new corsa exhaust. very loud but no drone. locking header bolts.

My solution was standard bolts & lock washers with a bit of RED RTV silicon on the threads.

The heads are aluminum, after all, so exotic steel isn't called for. I figured I'd use the standard grade, hex-head bolts and see if they worked and replace them with locking bolts as needed.

Well, that was 5 years ago and they're still on there and I haven't had a leak yet.

How many have done the install on jackstands?

probably most of us.

Once you get the oem manifolds out, it gets pretty easy. The biggest hassle going forward is the bracket for the dipstick and then the O2 sensor extension harness on the same side. The headers themselves almost fall onto the heads as the space is plenty large enough to just push them in place. I can take off a manifold in about 2 hours now (once the catback is out of the way). loosen the motor mount bolts as raising the engine makes finding some of the top row manifold bolts a little easier.

I was tempted to do the same once I noticed the stock bolts seemed to be "special" (light weight, something exotic?), but I had already ordered the Stage 8 bolts (which are kinda nice with their internal wrenching - Allen wrench - feature).

What are the stock bolts made of? Titanium? They felt very light.

I agree 100% w/ Mike!

I built my own dipstick "Z" brackets, and I'll make one for anyone that needs one; anything to support the Brotherhood! PM me, and I'll get you in the "Q" for a bracket.

Far as the O2 extension, I simply spliced a section into the stock harness, wrapped the harness in braided heat tubing, and routed it behind the heat shields protecting the fuel lines.

AND, to facilitate connecting the wideband O2 sensors for dyno tuning, I relocated the O2s so that they extend (more or less) horizontally toward the frame rails. (No worries about being "wiped off" by some kind of road debris. If getting 3' of air and coming down on the frame didn't tear them off, I wouldn't worry too much about them being vulnerable...unless I take the Vette rock-climbing...not likely.)

Anywayz... Let me know if you want me to whip up a dipstick tube bracket.

Paul.
