Header collector flange, v band, ball and socket, or standard 3 bolt?

What is the best collector flange and gasket.
My headers are 30 years old and still the standard 3 bolt.
I'm going to be reworking them and have an opportunity to upgrade to a ball-and-socket or V band. What are your thoughts?

Re: Header collector flange, v band, ball and socket, or standard 3 bo

On my Chevelle, the old junk headers currently on it are the three bolt style that we welded together and then used a band clamp between the collector and the pipe. It works perfectly fine that way. The 82' K20 that my Dad and I have has the Headman ball socket joint style. This also works very well, but if you don't use lock nuts, they WILL back off once in awhile, but at least there is no gasket to blow. I currently have a brand new set of the Hedman ball socket type headers ready to go on the Chevelle this winter. I would say that if you have the least bit of misalignment between the header and the pipes, the ball socket would be a better choice, otherwise either style is just fine. The one thing I will NEVER do again as long as I live is use the three bolt style with a gasket.

I had a 3 Bolt years ago, and they were nothing but trouble. Now I have Headman Hedders with the ball and socket and they're great.

I have Hedman Elites with the ball and socket. They work very well. Check them for tightness every time I change the oil . Never loosened up.

In 2006 I installed my 468 BBC and put New Hooker Headers 3 Bolt Type # 2455-1HKR /
and a Flow Master Exhaust Kit#17119 = 2.5 Mandral Bent with Super 40 Series Mufflers

The Engine was Rebuilt in 2013 and 2017

Still using the same Headers and Exhaust System, just put new Header Gaskets on at the Engine & at the Exhaust each time
Remflex # 2003 and # 8003

Never any leaks at all
