There are some stainless or coated tri y's available. Since your car is stock, this is the headers that were most commonly used when your car was new, so they would be a period modification. The tri y design offers a very good low and midrange power gain for your street driving.

I am in the market for tri y's myself and I've seen plenty of them on ebay. Just search ebay for 289 ford headers and see what you get.

You might try this link:

My $0.02
Those are the ones I went with, but mine were $229 delivered. They fit very well. My car uses the z-bar clutch linkage and is manual steering and brakes. I don't even think I scratched them putting them in.

We run ceramic coated MAC's on our '66 with very good results. They've been on for about 4 years with no rusting issues. They are designed for a 86-93 Mustang but fit the 65-66 body nicely.

If you have power steering or a cable activated clutch (if it's a manual), you have to be careful about which headers you buy. Some don't fit with power steering, and some don't fit with a cable clutch.

Where in PA are you?

don't forget the cost of modifying your existing exhaust, installing collectors, H-pipe, etc. Of course if you have access to a welder it's significantly less.

Nooooo. Either you have no towers or they are designed for a 65-66
. Factory headers won't fit those cars.

The ceramic heat coating is not just for racing. Headers make your
engine compartment very hot and the ceramic coat keeps more of the
heat inside the header. Heat is bad for your wiring and non-metal parts.
Plus tube headers are alot more noisy and the cheep ones are prone to leak
and not last very long.
Hipo headers (as mentioned) would be much better if you're not looking for all-out performance. You can get them coated so they don't rust too.

I have towers, and when I manage to dig through my receipts and find the model of the headers, I'll post it up. If you look at the link in my last post, you can see the headers from the bottom of the car.

thanks for all the help! I'll definitely make sure i go with coated headers and it looks like i have a lot to watch out for to make sure the headers actually fit as my car as my car looks like it has all the components to create clearance problems.

Thanks again

Whats the beneifit to the tri-Y thing? Increased clearance with only two tubes at the collector? Equalization further upstream in the tubes?

Am thinking on losing the exhaust manifolds for my 70 Mach 1 with 351C 4V and looking for nice ceramic coated or set I can have ceramic coated. Would like a pair that tuck in nicely and dont hang lower than the pan. Is there such a thing?

Tri Y's help balance out the horrible imbalance in 90* V8 exhaust pulsing. It doesn't fix it, but is an improvement. They almost always make better low end than any other header design, and always make better mid range. Top end depends on the design, but most are built for mid range so they lose out on power up top over LT's. Doug's uses a larger primary design so it doesn't get choked out at higher rpm, and I've seen them make decent top end power on SBF's, but the tri y design generally makes more average power over a larger rpm range, but less total peak power.

Do not go with Shorty's, they aren't worth it, no HP improvement. You want to go with a long tube header. I would go with a set of Ceramic Caoted Tr-Y headers. They fit well without having to bang them up at all and they give you plenty of clearance.
