I should probably know this after having the heads for over 25 years but: my W2 heads have two exhaust bolt patterns on them, does that mean I can use regular non W2 specific headers or do they have to be for W2 heads? Reason is I and going to dyno my spare W2 head 363 soon and I dont want to take my car apart to take the headers out just for the dyno and I am trying to figure out what headers I can use.

Yes. Though the standard header port shape is a disastrous mismatch, you could do worse than the adapter plate set up and standard port header. It’s that the exhaust does not care how it gets out vs the intake charge getting in.

Do you have the adapter plate for standard headers?

The W2 headers also come in standard bolt width (narrow) and wide for the bigger tubes.

Like an idiot I sold my old set of Tubular Automotive headers with the plates for standard and W2 heads a few years ago and now wish I hadn't , I have the junk TTIS on my Indy heads in the car now with no plates, I am mainly wondering if I can use regular head headers on the W2 heads just for the dyno. And thanks for the replies!

I have a set of plated tubular automotive headers w/plates for sale. If your interested.
 
I think Hells Gate Hot Rods in Viola, ID still makes header flanges for the W2 ports in both the wide and narrow bolt pattern in case you want to do some fabricating......
 
Just remember that the plates take special counter sunk bolts to attach them.
 
My plates use a countersunk socket head bolt. I have no idea if the are OEM to the plates, they came with the headers I bought from one of our members 2-3 years ago.
 
Viola Idaho ? Huh ... didnt know.

Unless there is something special I can’t see in the pic those are just standard flat head socket cap screws. Should be able to get them from any decent fastener vendor. I’ve used thousands of them over the years. you want to be careful about how tight you torque them because that large area on the angled face gets a good grip and they don’t wanna come back out.

My local hardware store carries them, and I live so far in the country the hoot owls and chickens fornicate.

Mine too, I found the ones with a hex / allen head are better to use, better to tighten with an Allen wrench . I always felt I couldn't get the ones using a standard flat head screw driver tight enough.
 
I can't tell you how many places I haunted trying to get the socket head bolts for my plates when I installed them. Big box stores, mom & pop hardware stores, parts stores & the best was Fastenal, they wouldn't break a package, wanted to sell me 200 of them. LOL That's why mbaird & I struck a deal on the ones he has, so I will have a "few" extras.

Get them with Torx type heads if you can find them. A lot less likely to strip out than hex. I can't tell you how many I had to use a punch, chisel, or drill on over the years, especially stainless. Torx can take a pretty good beating and the drivers seem to torque out less than hex or God help you, a Phillips.

Online, try McMaster-Carr or Bolt Depot next time.
I won't use Fastenal after the local store refused to sell me anything unless I had a $25 minimum even if it was instock in that store. I told them they just lost $10k a year in what I would order from them for my company and the idiot didn't even blink. Said it was too expensive to process small transactions, as he and the other guy stood around alone all day.
 
The ones I have are hardened which might make them harder to find . Either way you can't beat my price ... free + shipping ...lol
