Assuming I was sent the right headers, supposedly designed to fit my '68 302 perfectly, don't buy the new Doug Thorley headers. They're expensive but very high quality, apparently don't perform that well except on stock engines (according to Alex, I think), and most important of all ... THEY DON'T FIT! I had to cut mine and reweld them to clear the transverse transmission brace thingy.

88300 Hedmans are best bang for the buck. 
Others are better quality and depending on the rest of your combination will perform better like Tri-Y's or Hooker super comps, but are about THREE (3) times the money. ------------------

I put the Hedman's on my '65 coop. They fit well. I needed the power steering ram drop bracket and we had to unbolt the driver's side motor mount to get them in. They're pretty close to the starter, but there's enough room to get some asbestos wrap or a heat shield of some type in there. Only one bolt on the #2 cylinder requires I take the spark plug boot off to tighten it. The rest are readily accessible. All the spark plugs are reachable with the headers on. They have a bizarre-shaped gasket because the header tubes are oval-shaped at the flange. If you are planning to home port your heads, my recommendation would be don't grind the exhaust ports out as wide as a standard Fel-Pro gasket as the header tubes are just barely that wide themselves. Leave a little extra meat on the sides and work on raising the exhaust port roof. Any port matching at all, however, will probably require the Hedman gasket to be modified. I carved mine out to match the exhaust ports, but now I'm not sure if I have an exhaust leak, a vacuum leak, or a loose rocker arm, and it's too frickin' cold out to deal with at this time. Does anyone have a specific gasket recommendation for use with the Hedman 88300s? deadhead

First and BEST choice for Hedman or Hooker headers is 5930 Mr. Gasket.
Second choice is 253 Mr. Gasket.
Third choice....see first and second choice. ------------------

Guys,
I was advised not to port match to exhaust gaskets on the "standard abrasives DIY porting website"
they said the step helps cylinder scavange. Sounded interesting, do you have an opinion?I would think it would depend on the engine but I cant imagine a big step is a good thing myself. ------------------

I believe the early SBF exhaust ports as cast are way too small. Tiny would be a better word. Mine heads also had the thermactor hump, which is reason enough to get in there with a grinder. I didn't touch the floor of the exhaust port, but widened the sides and raised the roof using a D-shape. There is a great article on porting an early 289 head on the Ford Muscle website. It'll cost $5 for a month trial membership, but I thought that one article was worth the five bucks.deadhead
