Ive been griping about $600 Hookers....CFI clued me into the Hedmans this morning..Flanges, pipes all look the same and much cheaper. May go that route, car doesnt know what brand the pipes are.

Did some checking today, and the difference between Hooker and Hedman is the Hooker primaries are 16 gauge steel, the Hemans are 14. Not enough to ever notice.
Still need to verify the flanges are 3/8 thick..Hookers are 5/16
Every retailer I spoke to said comparison of fitment was a tossup.
Hedmans are looking better and better.

Charges $180, top quality coating...Does them one at a time, no produciton stuff.

My experience when adding headers is that along with a free flowing exhaust system it moves the bottle neck for the movement of air from the exhaust system to the intake system. I would expect you to really feel a difference in how quickly the motor will rev and how much more mid and upper rpm range power you will have.
The stock intake system on our L98's is, from my reading, quite limited to 4500 rpm for all practical purposes and is well shy of the redline of 5500 rpm. So by adding the headers you should gain the maximum bang for your buck and still be shifting at the correct rpm without getting into the redline. Safety and longevity!
The only draw back I've experienced is that the under hood heat is so intense it destroyed a good starter in six months and considering all of the tightly fitted plastics under our hoods, I will be paying for the ceramic coating for sure. You might also notice a more pingy sounding exhaust from under the hood, but it helps the permanent smile once you feel it.

...the untouched "D" shaped exhaust port measured 1.35" wide X 1.30" tall. The untouched header size right at the flange measures 1.22" wide X 1.55" tall,...

Yes, it was he who told me about them. They were the Husler series...These particular ones werent for a Vette but a SBC nonetheless. I think the Hedmans are a better value (and Im a long time Hooker header fan)

The last time I purchased a set of headers (which was longer ago than I care to admit to) I paid about 150 bucks. I'm looking for a set now for my 91 L98 Coupe and can't find any less than $950! What happened???
Am I correct in assuming that long tubes are the way to go or is that all that's available. Also, I'll draw on your collective experience...who makes the best ones for fit and performance?

Easily more than enough. Like I said, mine will only need a mere .015" "blend" which in all honesty, is probably a waste of time even worrying about, since it's so small of a difference. But since I have several weeks before I start doing any part swapping, every little thing like that will be taken care of to kill some time.
