C6ae-r heads

Make your Cougar run faster, handle better, and jump higher... okay maybe not jump higher. If you feel the need for speed, this is the place.

Ok gotcha... Sorry for the confusion and all the noobish questions.. this is my 1st classic. It's far from concourse just want a nice driver that performs well. And I'm learning these FE motors are way different than anything I've worked on
The only foolish questions are the ones that don’t get asked.
Thank you!

Does anyone know off hand which headers will fit these heads and work in the cougar? A guy in fe engine enthusiast says he has a 67 with these heads and headers but doesn't know what brand.

They have the same exhaust ports as any of the low performance 390GT heads. They need to be drilled and tapped for the bolt pattern used in the Mustang / Cougar / Fairlane / Comet. Then you can use any header or exhaust manifolds made for 67 - 70 Mustang / Cougar.

That's the 14 hole right? I think that can't be without relocating the top holes right? On these heads the vertical home are in alignment.. are the 14 hole verticals different? I'm not trying to question you Royce. Just trying to wrap my head around an engine with so many different heads, this is new to me lol.

"Ford Power Applications" FPA makes a nice header. Ive used them in several cars with no fitment issues. They fit a whole lot better than Hooker's.

Basically you have to position each exhaust manifold on the cylinder heads, mark the holes, drill them and tap them 3/8-16 NC.

This photo is an 8 bolt head that has been drilled for either 14 or 16 bolt pattern. In your case you will have to plug one hole (#4 cylinder, top bolt hole) with a piece of cut off bolt, which is sealed in place with RTV, then ground smooth with a sanding disc after the sealant is dry.

This photo shows a plug installed in the #4 lower hole.

Make sure you have your socks off when you count....cuz if I remember correctly -R heads do not have the boss for diagonal bolt holes on all the ports...then there are -r heads which R different from -R heads....see what I did there ? Here are true wirds of wisdom ....No headers on FE street cars....what fer ? The added heat....the added noise...the added maintenance headache ? The added power....you will not feel it....Pay a machinist to true up the exhaust face of your tall port heads ...match drill them to CJ Exhaust manifolds and live in peace and harmony....the ONLY other optiin would be drop BIG coin on really top shelf headers like FPA's ...Really spend your money smartly ..forget the FE set up ...FE = f"=@kn expensive...put a stroker small block in there....a nice 408 with short tube headers....put a set of 6.5 litre badges on the fender and smile smile smile

You are mistaken. The C6AE 6090-R heads have the bosses for 14 bolt / 16 bolt pattern.

Not all of them do..I have had a few sets that had the boss and a few that did not......I still will admit to not being 100 % sure about there being a difference with 14 bolt or 16 bolt....I do know...my first pass with a lo buck solid cam cleveland pulling hard ALL the way made mevforget about all the coin I spentbtrying to get similar level of power from a 390
