Question Header?

I'm restoring my '72 GMC with a 402BB. Should I put on Headers or keep the stock manifolds on? I've seen on the board here where some owners have had some problems with headers loosening up and having to keep retightening them over and over, and burning up starters. How many times and how often do they have to be retightened? I was just wondering if it's worth it , to put on headers peformance wise etc.? Thank you everyone.

I tighten mine every time i change my oil.

Headers can be a hassle someitmes....but to me they are worth the cool sound and extra power that they give your motors.

To me headers are always worth it. Better hp,tq.throttle response and gas mileage. Get some good header bolt locks like Stage 8 brand and good gaskets (along with good headers) and you will not even think about them. As far as the starter goes, yes sometimes they pose a problem will heat soak. This mainly happens will full length headers over shorties or blockhuggers. You can get heat wrap for the starter, move the solinoid(sp) or get a gear reduction starter. Some people don't want to go through this but I always thought it was worth it IMHO.

I went with the Dyno Max cerama coated headers ,I would suggest if you go with headers get the Percy Dead soft header gaskets .

I haven't tightened my headers since early june.... I would suggest soft aluminum collector gaskets for the collectors and, stock manifold gaskets for the flanges to block gaskets. They hold a better seal than the paper header gaskets and only cost 3-4 bucks from the local parts store. Another plus is, to change them you don't have to unbolt the header.... just back the bolts off enough to change them. I think it was longhorn man that turned me to the stock gaskets. I will never go to anything else.

Yeah, that's how I do it.
As for header bolts backing out, I never seem to have that problem, I used the cheapest parts store header bolts I could find, and installed them dry with a wrench, that was 2 trucks, 2 sets of headers, and 3 engines ago, and I have only hade one bolt come a little loose.
I know it is a common problem, but I never seem to have to worry about it.

speaking of Headers how often do you guys have to change out your flange gaskets, i got new ones when i got my new pipes about march, and now i need new ones you can hear them sucking air and i already checked the bolts for tightness.

Get the dead soft alluminum ones, and they'll last longer than your engine will....regardless of how often you drop your exhaust.
They may cost 20 - 35 bucks, but you'll never replace them again.
