Which heads I have a multiple choice.
OK, right now I have a 66 352, that I am converting into a 390. Right now the heads on there have the casting number C6TE-G, I have the high compresion 360 car pistons, 390 rods, 390 crank, and CRN-343901 cam, Ready to install, as soon as I winter her. I have a choice on heads that I won on ebay. I reserched the crap out of my BIG BLOCK Ford engine book by Steve Christ, but the heads on a motor I have no Idea about combustion chambers, valve sizes, or port demensions. I am hoping someone can help me male the best discision and the best head from the bunch. Here are the choices. C8AE-H (4 of them), D2TE-AA(2 of them),C6AE-H (4 of them), C7AE-A (2 of them), and C4AE-6090 (2 of them)
<O
I am thinking the C4AE-6090 with 73.2-76.2 cc intake 2.185/2.195, ports 2.78X1.38, exhaust 1.723/1.733, ports1.86X1.30, but then the C6AE-U Are high compression 67.1-71.1 cumbustion chamber volume. On a side note I can get all these heads for 70.00 plus shipping. If any one wants these and are serious, I will get them for you at 10.00 per set plus shipping to me then shipping to you.
Thanks for the help, I am good about everthing else on a motor but when it comes to heads, I am clueless. Sorry if I sound stuppid

Well, what's the letter after the 6090? Go take a look. I'd bet it's C4AE-6090-G. That would mean 2.02 / 1.55 valves. The regular C4AE-6090 without the letter is also standard 352 / 390 heads with 2.02 / 1.55 valves.
Since you have the book, look on page 55 about your heads. The C4AE heads on page 56 are 427 low riser's. Dollars to donuts you dont have 427 low riser heads. If you do though, you can forget about using them on a 390. The valves are way too big.
Now, the C4AE heads DO flow better than the later heads. You will have to get hardened exhaust valve seats put in too. The C4AE heads, if they're not 427 low risers, which i'd bet they're not, are definately the choice. Get them ported and you have one heckuva cylinder head!

The C4 and C4-G heads are both the same. Chambers ,valves everything. The C4-F are high riser heads. All the 427 lowirser heads are C3 castings cept for the K which are HR's also. 1.65 ex valves can work but a bit risky as Rusty said. Bore notching would be required. The D2-AA and the C8-H are also the same just the D2's have hardend seats. Both have the same cc chamber. The C7's have smaller chambers and the C6-H might be C6-R's which can be made into a good head also. Again both of those have the same size chamber. But I have heard there was two C7-A castings with different chambers but have not confirmed it. C6-H does not ring a bell right now so maybe check if they are R heads possibly? Russ hogged out a set of C4's maybe he'll chime in for ya. G.

Well as G, said...I would go with the C4AE-G's, they do have a larger chamber in them..there 71.2 to 74.2 CC's..but with that said you can control your CR with the head gasket thickness...
Properly Ported C4's will out flow the Ported CJ Iron Heads....in which tho maybe over kill depending on your build....I havent read about it yet.. Now my heads "ported are flowing about 290cfm Intake and about 200cfm Exhaust @.600" Lift which is where my cam is...
But it all depends on the porter!! and what kind of day he's having..I have seen other porter's only get 260 to 270 max out of the Intake cfm... Now I stayed with the standard CJ size intake Valve's, But I jumped up from a 1.66 Ex..Valve to a 1.73" valve as it worked best for my combo!!
I may be Bias..but if you plan on a Ported Iron head.. the C4AE-G's and the C6AE-R's in that order make the best bang for the buck!!
And if you decide to go another route and dont choose the C4AE-G I'll gladly buy them from you..I could use another set!!
Good Luck with your choice!!

My $.02's....
With what you will pay for the heads plus shipping plus clean up, you can buy a remanned set of the D2's ready to bolt on and will work fine based on your build/internals with a stock or Performer intake. You can probably step up to the RPM manifold too. If you want to set the heads up like the aluminum RPM's, are you doing the work yourself or having the machine shop have at it? The manifold and heads are where your bigger increase in performance are going to come in. Again, compare the cost of getting to the end product with just buying a set ready to run.

Well Matt, I was going to have Scott V, do my heads..cause in Kentucky I can get free time on the Super Flow 600 Machine..But Scott doesnt do the Machine work for bigger Valve's..He jobs it out...I was going to Les Schmader up in PA.. But then I found a guy in Richmond VA, that does a good Job....
I mat end up selling my C4's and buying the Canadian Dove's?? I dont know yet? But as mentioned above..the out of box wont..flow as good as a ported set of C4's..I think I have about $900 total in my heads...But a set of ED Heads ported will out flow the C4's but not by $1000 worth... JMO..

i thought you had Les do your heads, i was confused at the time when you posted about buying the big guy a steak or whatever. Gotta love forums, talkin about steak in the FE section.
These DOVE heads, you got any pictures, specs, prices? If i wasn't so poor I like to have those c4 of yours. And o/t as always, I am surprised your dynamic compression in the 433 is 7.56. That has 89 octane all over it, Russ you can't have that. Build that beast up some more, 11:1 static and 8.5-9.0 dynamic. Think of the boost in power for the slight increases of cost in premium gas. lol

Russ, man you are getting greedy! I am somewhat of a flow bench racer, i would want some flow values on those dove heads. If you are going to play like scouder, you need them stage 2000 edelbrock beasts, and a bit more cam.

Matt, the 428 Hi velocity heads by dove will flow 290 cfm at .400" valve lift and maintain that thru .600" lift...and I'am sure with a little work they flow alot higher at .600" where my Cam is...
But the ones I really like...but I havent found any low #s on them is the Med riser Blue thunder heads..BT make as far as I'am concerned the best made head on the market for the FE's... But I have yet ..like i said to find stock flow #s and some ported #s for them... Those would be the 2 I would consider before I sold my C4's..and the only reason I would do that is maybe pick up a few more CFM..and be able to run a little higher CR without detonation..maybe around 11 to 1 ?
As the build is now with the Iron heads..it will still want at least 96 octane...No biggy cause it wont see any one way trips over 250 300 miles? ***** if I can afford the gas?? LOL..

Oh and Greedy!! LOL.. and Matt I'am borderline now on my Cam...as it is it will only pull about 8.5hg's of Vacuum at idle...So I'll have to run a vacuum canister....
Its CompCams XE284H .584"/.588" lift 284*/294* Dur. and 240*/246* @ .050" and that will be with a 2500rpm stall..

well Russ, If mr Francis wasn't such a hermit, we might have some blue thunder info. I also think highly of blue thunder, but theres never any flow numbers. I will see if i can scrouge of some for the MR's.
