Hi Vman, DanR here! Here is a good Header Gasket for the 2.8 V6's : Hooker Header 10828HKR
There are a couple other numbers on the package 4526307 & AM04762027 Not sure the relation other than assigned as a made in a Mexico that work nicely with my straight back headers...

Greg, What is the part number for the ARP Bolts you purchased?
I found some ARP's and thought they were either shorter or longer than required.
Besides the cost was extremely high if buying in a quantity for more than one set of headers.
I found some M10 1.50 25 (lg) 12 pt head for less than half ARP's that I will be providing with my Straight Back Headers.

I ended up following recommendations by getting SAE bolts. They were cheaper and more readily available than the metric counterparts.
For 3/8-16 with .75" under head length, ARP's part number is 100-1108. It's about $23 per 16. The hex head is 5/16˝.
For M10-1.5 with 20mm under head length, ARP's part number is 662-1001. It's about $18 per 5. The hex head is 12mm.
Before figuring out the ARP thing, I used cheaper bolts. They cross-threaded and turned into pudding. It was a serious waste of time and money. The ARPs were worth every penny (if for no other reason than the tiny 5/16 wrench fit better in and around the headers). And with Amazon Prime free shipping, they were at my door the next day.

SAE vs Metric or Versa
Greg, From what you said you went with the 3/8-16 SAE first, discovered they stripped, then bought the Metric at $18 per 5.
Well, I did not like the SAE 3/8 for the Cologne Engine because the entire engine is Metric. I have tried for more than a year to find a good deal on Metric header bolts. Just last week located a company and ordered a hundred of them. Metric M10 1.5 with 12 point head 24 length and hardened.
Cost is less than half the ARP. Shipment is due next week. Will let you know how they work for me.

To clarify, I went with parts-store grade SAE bolts first, discovered they stripped, threw them as far as I could and upgraded to the ARP SAE bolts.
Incidentally, I purchased 12-point SAE bolts first and discovered that I have no way to wrench them on (since a socket wouldn't come close to fitting in about half the bolt locations (and I don't have 12-point box wrenches)). So if ever you decide to go the SAE route, let me know and I'll share my wealth. I believe have enough to do two cars.
