428 Cobra Jet Cylinder Head Identification
I also own Low Riser, Medium Riser, and High Risers. So don't get snippy. Not only have I compared ports side-by-side, but I've matched them up to plenty of intakes. Don't forget to show us those C9 castings!

I stroked the engine today, and it dose indeed have the 428 crank in it. While I was messing around with the truck I measuerd the ports on my heads and the ports on my new intake manifold, The ports on my heads are 1/4" taller than the ports on on the manifold. It shouldent be a problem to port match it. Right?
And a couple questions about my manifold. I couldent find any casting numbers on it, just the firing order and FoMoCo. And I cant rember what I was told when I bought it a couple years ago.
Can yall tell me if it is a single plane or a dual plane manifold?

No, it has a 410 crank in it since both engines had a 3.98" stroke.
That manifold is gonna suck on the street, the open plenum and single plane are not good for the for low end or mid range. The spacers don't help either.

I knew that the spacers were going to have to come off, mostly just so I could close the hood!
I was afraid that it was a single plane intake.. How bad will this manifold kill my torque compaired to my single carb, iron intake manifold.
Its not really a street truck, I spend most of the time playing in mud and off roading. Dont think this matters though, according to my book single planes are really only good for racing.

That manifold started life as a dual plane, but some nitwit cut out the center divider in the plenum and hogged it out. You will be lucky if that manifold starts working by 3500 RPM. Putting a pair of Holley 390 CFM 4 barrels on it would help a bunch and still be way more carb than you need. Even a pair of 2 barrels would work good. I did that on a cross ram manifold on a drag/street car once.
410 CID @ 6000 RPM only needs 711 CFM

6V's can be much more streetable, but you must do your homework concerning carb refurbishment and tuning. I ran a 6V for a couple years on a 410 in a Cyclone GT and it was blast. Get your wallet ready.

Happy now? Good!
And now to clear up the C9 heads for the newbies: the C8AE-H heads were used on 360's, 390's, and standard/Police 428's from '68 to '71, and was replaced by the D2TE-AA head in '72, which ran through the end of light truck production in '76. So, there are no C9, D0, or D1 heads in the FE world.

Ok so when I go shopping for intake manifolds and carburation again, is there any particular casting numbers I am looking for so the manifold ports will match up to my
C4AE, 6090G heads?
I have a set of Hooker headers ( Hooker Headers 6906HKR - Hooker Competition Headers - Overview - SummitRacing.com ) I bought for the truck along time ago, I bought them for a 390 4X4 truck of my year. Will these headers fit my C4AE heads??
What about when I order parts, anything on or around the heads, should I search it as a 64 Galaxie 390/427?

Those headers will probably have a mismatch to your heads, but may work depending on how you approach the gasket situation. I have no direct experience with that exact combo.
