I have a 64 F85 with a 455 and a turbo 400. The guy that I bought the car from said he got the polished SS headers from eBay. I don’t know who he got them from but the fit and quality seems very good. They have a very heavy flange and don’t rub against anything. I’ve had them for about four years now, and haven’t had any issues with them. I also have a mini starter. I use a Napa gold short oil filter #1258. Hope this helps.
I purchased some of them and they fit just fine and were really good quality. These are the ones I got. https://www.ebay.com/itm/382447780124 They did arrive with a dent and I accepted a $50 refund.
any pictures of them installed. How low do they hang?
There are pictures of them installed on a small block on this board, or were posted here. Do a search. Now, with that said the will be similar to any other header on clearance, and are pattern copies it seems of Hooker Headers. They look really nice, so buy them. Buy 2 sets if you also want some nice wall art
No not installed yet they are still being shipped.
the headers on my ‘64 were beat to perfection with a hammer by the prior owner and fit when I had an SBO. Anyone who has a ‘64-‘67 knows how hard getting headers is for SBO. These were already pre-beat and fit SBO but I kept them until now for BBO. Time to move on.

I would like to point out most headers have their share of dents and bangs, and it doesn't hurt the power they produce. Being shiny stainless it still should look shiny. They will change from shiny when run anyway after awhile, but can be polished back to shiny. Expect a struggle getting any headers on anything, and appreciate anytime its not that bad.
They were on the car when I bought it. The guy that I bought the car from said they were eBay headers. I wish that I would have asked him who he got them from but I didn’t, dumb on my part.
I have a pair of the non-stainless ebay headers on my 67 with a 350 block. I needed to dent tune the driver side to clear the motor mount and the mini starter electrical connections. I added a homemade O2 sensor bung and the collector wall seemed to be thick enough to last a while. They only hung down maybe 1 1/2 inch below the crossmember so on a big block that shouldn't be as much of a problem. Here's a pic from the front. However much taller the big blocks are is how much shorter the headers will be.
I took a chance on the Ebay cheap headers. Fit perfect on my 70 442. No adjustments needed.
I would say those headers gives whoever buys them bragging rights on looks, and at a price (with free shipping) so low it's like you stole them. This was true 10 years ago, let alone with all the inflation since then including on shipping.
I bought a set for the reasons above. Someone on another site didn't like the dent in the collector for shift linkage clearance, super minor IMHO. I plan get these in my 70S in the next month or so. I am going all Stainless to the tail pipes, including dual 2.5" cats. I also just installed the Chinese Stainless copy of the direct replacement shorty header for the 5.2/5.9 Magnum on my Dakota. They fit and look really good so far, after some run time.

And a reminder that mufflers are the main choke point on flow, and generally only flow about 70% of the same open pipe size.
what are your thoughts on installing a 18” header collector extension with a removable “cutout” plate at the end and keeping the rest of the exhaust system.
is this effective in gaining back the 70% when desired

The exhaust has to be going in a straight line, to really work well. "Cutouts" have been around as long as I have, that open 45-90 degrees to the exhaust pipes, but much like H pipes they have a problem at higher flowing rpms. The don't add power at high revs. Good for lower slower speeds, but not higher.
It you run the gases into a dead end like with the extension that would cause turbulence and restricting flow even further would be my guess. Now using the 18" extension, and then reducing it down for the mufflers might help, since the exhaust is still going straight and you have added a lot of extra volume for the gases to go into.
The only other way I can think the extension would work we is putting a cutout on its end, and then y ing off a pipe for the muffler system off of the extension. But that would make the system loud when the cutouts were opened up.
Another way around the mufflers restriction would be mufflers in parallel. Side by side mufflers off a Y pipe I would think would work. BTR did that on his street 442 many decades back now tucked away behind his rear bumper. Big mufflers generally flow better than small ones, since their is more space in them so less restriction.

I had been thinking a 3” header extension with a cutout at the end coupled into a 2.25” exhaust would be very effective. By virtue of the coupler being much more restrictive that the cutout. Even at high speeds the exhaust would avoid going into 2.25” and exit the path of least resistance. But maybe it’s nonsense like you say because the header extension needs a straight shot out. Not 45 or 90 degrees inline with the rest of the exhaust to the mufflers

Thanks, this looks nice and clean. I'm going to do a 3" systems with Super Turbos to keep the sound in check., but tail pipe with drop back to 2.5" to make it easier to get around the back and to the tips.

Here's some Hookers on my '72 VC, 455 5-speed. Nope. Drop spindles have to go, but I don't think that will make enough ground clearance. Collector flanges are welded. Duh..
Walker Quiet Flow (walker 22100), with 2 1/2 in and out, with a case length of 28 inches is the best turbo muffler, in my view for 2 1/2". It's the biggest case at 28 inches, which should be good for flow. Turbo mufflers in general will get a little louder over the years, from what they were when new.
Sadly, I went to order these and there SOLD OUT at the moment. I think I would like these to replace my crustys on the car. BUT really don't need till fall as that's when engine is coming out anyway.

Check out the latest Engine Masters episode. They do exactly what you mentioned, and with the cut out opens it made almost the exact same power through the full RPM range and headers with an 18" extension. This was on a BBC with 3" exhaust.

Post the link I want to see this. But if you are talking a cut out open at the end of the extension that is no longer a muffled system. Still I would like to see the results. In my mind the real trick is full power and with no noise whatsoever from the exhaust, or what I think of as silent but deadly.
It may have something to do with my past history, as the first car I outran in a safe street race at the age of 15 had cutouts open, a cam (it thumped), and 411 gears with a 3 speed with overdrive, and I outran him with my oem muffled car. He had a 265 and I had a 283 powerglide. He made several mistakes, like spinning bad off the line and then he failed to shift into overdrive and that allowed me to scream past him on the far end (I was still in low gear). Beginners LOL

Great timing now I can justify my MotorTrend subscription which I haven’t watched and have been paying for two years. I can move forward with plan for my headers, extension, and exhaust cutout.
