Hedman drop right in and are a good price, but they do hang very low. You can see them under the car in top pic.

IMO, Headman headers are a good value. I find myself using them all the time. The choice is made easier every time I go down a price list of what is available for a given car.

I like hedman headers too. Priced right and made in USA which unfortunately is getting more rare these days.

I have had great luck with the hedmans as well..

I am running the headman headers as well. they work great and i have not had to tighten them other than the first time they were installed. However, they are low. they do drag on speed bumps.

*****you will also need to get the power steering drop bracket if you have power steering.

Having worked in the exhaust industry for 5 years building custom exhaust I can say that I am not a big fan of headers. Between putting headers on for people that want them and taking header off for people that hate them I have literally done hundreds of headers. They tend to get loose at the head and then blow out the gasket. The 3 bolt collectors are notorious for leaking and scrape on speed bumps. I have never heard of a cast iron manifold rusting out. I have seem many headers rust. They can be difficult to install although a small block Mustang is not that hard to do. The performance advantage is minimal over a good set of cast irons.

I usually figure about 2 hp per cylinder on a stockish engine as well as an increase in fuel mileage..That hp number goes up in leaps and bounds once you start to modify the engine..There was an article in one of the mustang/ford magazines where they modified an engine with alumium heads/intake etc but kept the Hi Po exhaust manifolds thinking that they weren't really that restrictive...When they couldn't get very good numbers on the dyno they finally put on some long tube headers and the hp increased by over 90 hp!....If you look at the engines in new cars most of them are running a tubular style header..They are lighter and the increase in hp and gas mileage are too important not to run them in place of restrictive cast iron units..

Sweet thanks for all the input. Looks like I will be looking into a set of hedman headers!

My son used a set of ceramic coated mid-length Hedmans on his 66. The ceramic coated Headmans are for SURE better quality than their natural counterparts.

We ordered BOTH the ceramic coated and the regular, ended up sending the regular ones back after a side by side comparison. The ceramic coated headers were of better quality, even the flanges were thicker.

IMO copper gaskets help TONS in my tolerance for headers. They don't loosen so often, and the gaskets NEVER blow out. So long as you don't let them leak for a really long time, the need to change gaskets is a thing of the past.

There are few jobs that **** me off more than having to change a blown header gasket, especially when a POS cheap *** paper gasket needs to be cleaned off of a header that is a bitch to R&R..... And even if you do end up needing to change a copper gasket, you never need to scrape one off a head or header....
