Those heads were used on 390 GT And 428 non CJ Shelby applications, and many other 390 Applications. They have bosses to support drilling them to 16 bolt, even if they were 8 to start with. Also have the bosses for Thermactor drlled or not. This is by my old memory.

Not Cobra Jet heads

The C8AE-H is the most common of all FE head castings. Used on all low performance applications in 1968 - 71. Not worth much.

I will also add that the C8AE-H never came as a 16 bolt head...

They did come with a 14 bolt pattern or an 8 bolt pattern. It is common to find them redrilled. To determine if it was an 8 or 14 bolt head look at the outer upper bolt holes. The 8 bolt heads have the outer bolt holes in line with the inner two. The 14 bolt heads have the outer two bolt holes drilled slightly lower so they are not in line with the inner upper holes.

My '68 Torino with original S code 390 has the C8AE-H heads with the factory drilled 14 bolt exhaust mounting flange & air tube bosses drilled. (As a note the proper block off bolts for the air injection bosses IS still available from Ford). Improvments can be had by fully porting & the installation of the CJ size valves (2.09 & 1.66). My heads are fully ported & have the 2.09 & 1.66 valves. Valve un-shrouding of the head & on .030 over blocks on the top of each cylinder
is recomended & also what I did.

On a side note NOT all FE or FT heads have enough iron cast to the exhaust flanges to drill for 14 or 16 exhaust manifolds. I have a set of NON GT C8AE-H (8 hole) heads that don't have enough casting to drill for the 14 or 16 bolt pattern.

I find that VERY hard to believe. All later head castings are designed for 14 bolts

June 1 2010, 6:31 PM 

Starting with all revised generic 66 castings (like C6AE-R, but I am not saying all 66 castings) the heads are designed for the 8 or 14 bolt pattern. If you have a C8AE-H that is factory designed for only an 8 bolt pattern then you probably have the only one. I find it very hard to believe it exists from the factory and am more inclined to believe you are mistaken about its design or the number or somebody modifies it. I would need to see a picture as I have seen thousands if not tens of thousands of these over the last 30 plus years and never have seen a C8AE-H casting that wasn't cast for both patterns. BTW, the Thermactor port plugs were obsolete from Ford (unless they have rereleased them recently) but they are still out there. Hawkrod

Hawkrod I will have to double check the the heads again. But I am pretty sure that a couple of the bosses don't have the meat needed so the extra holes can be drilled. I know for a fact that one set of heads I have won't accept the extra holes though I don't know what their casting # is at the moment. Maybe it was a casting flaw or something.

As for the air injector block off bolts I JUST got a couple weeks ago 2 packages I ordered from my Local Ford dealer. What is interesting is the ones I got like 10 years ago came in small cardboard boxes the ones I just got came in heat sealed bags from Ford. Both the box & the bags are stamped with the part # & Ford logo.

Now can someone please tell me WHY there are 6 plugs/bolts in the package when the motor uses 8. Did Ford use these in another earlier aplication like a 6 cyl engine???? My understanding is that they were ONLY used on the 8 cyl motors.

Dont know if Im going to look for other heads or may be just clean them up . they have the 2.09 intakes &1.65 exhausts may clean up the bowls. What do you think aboutraising the roof on the exhaust ports about 1/64 to 1/32 of a inch and cleaning up around the flat spot by the place where the thermactor tubes would go (mine arent drilled) Also thinking of a cam 531lift on intake and 515 exhaust with 242 & 257 duration with 107 lobe angle This will be in a 67 Cougar GT 4 speed so a pretty light car just wantd to know your thoughts . Dont plan on it being a 1/4 mile killer just a nice weekend cruiser that can hold its own and be fun for now maybe more later on . thanks again Arnie O
