AUGUST 02 MUSTANGS& FORDS MAG
A fellow by the name of Mark Jeffrey with Trans Am racing in Gardena California did a build of a 69 351W, Ported iron heads with 1.90/1.60 valves. A crower roller cam with no mention of specs anywhere in the article, and 10:1 probe pistons. = 426hp. Does this sound legit?? The second part of this post (the whine) > Everyone else totally let down by the state of our car magazines. Back in the day, I loved BRUSA and Super Ford. All of the magazines now seem to be tied to the aftermarket to sell the latest trick of the week.

That IS the stated goal of goal of magazines.
Magazines want to sell advertising space. This is done by producing articles that are more "press releases" for manufacturers than technical info. This is one of the reasons why you see all buildups feature aluminum heads....
Also Holley stopped giving away carbs to magazine writers, so you see demons on every test.....

I think 426 hp is very doable with the old C9 heads. My old windsor with flat tappet cam was running them, I never dynoed the motor but it ran as quick as 11.18 at about 3100#. I'm thinking that equates to about 450-460hp.------------------

Rustang, how much was done to the heads in the way of porting?? Professional, home-done, none?? How much compression? Im hoping to run around 12:1 . Im really hoping the engine will have enough beans to get us solidly into the 11's. Im going to be running a transbraked C-4 which is going to eat up a lot of cash, so no aluminum heads for now.

The heads have 1.94/1.60 pro-flow valves, porting was done by a local guy, and the ports are surprisingly small compared to a set I ported about the same time. I think the best thing about the heads is the valve job, which is radiused with a very small seat. Compression in that motor was around 12:1 using the old Speed Pro.210 dome pistons. (the heads were milled about .050").
Oh yeah, one word of advice, if you are going to do a set of factory heads from scratch, with screw in studs, guideplates, seals, valve, springs, porting and machine work, it'll cost about the same as buying a set of lower end aftermarket heads

Yep, and if you have them ported as well, you're into the mid-range (cost) of aftermarket heads. Those aftermarket heads will likely flow better than ported iron castings, cool more efficently, weigh half as much, and promote more efficient (powerful) combustion... simply making more power. Just my humble opinion, but I feel that the aftermarket boom we've seen in the past 15 years has made our hobby so much more 'rewarding', especially due to the cylinder head market. Our SBF's no longer have to carry around that 'expensive to build' tag that they once did, and I for one am very thankful for it. The more affordable internals have also influenced many of us to stroke it  but the heads are really raising the standard. Again, JMHO  ------------------

I also got those mag's back then, but my favorite was "Super Stock and Drag Illustrated" (or whatever it was called right before it's demise.) When Peterson Publishing, now owned by/called Emap or whatever the mag pimp is calling itself this week, started buying all the competition and shutting them down, and started using the same core group of writers for everything, I stopped buying ANY magazines. I refuse to buy a Ford magazine when the writers are also writing articles for Stupid Chevy, Mopar whatever, Ricer's R Us, Low Ryder, and every other magazine that the parent company owns. Plus, like was already stated, all the 'tech' articles are now are advertisements with over inflated results for whichever company gave them the most money for the month. IMHO, there isn't a car magazine on the shelves nowadays worth 1/4 of it's price.

V-8 Thumper: Thanks for the cost info but, the only thing I will have to pay for (other than parts) for the heads will probably be the valve job. Everything else will be done for free. So the monetary comparison is nill for me thankfully. Thats part of the reason to stick with the iron heads if I can get into the 11's with them. Its going to free up cash to be used for real good c-4, and maybe a roller cam.
