I really need to get rid of my windsor heads and get something that will make good power. WHo has had good luck with what heads on a 347 or even 302. I am kind of loking for the best performance for the dollar not the bottomline best head.
I run AFR, I think Stephen and Jim rum edelbrock or something like that. I think all the aluminum heads are about....."about" the same. All the comparisons I see in mags. there ain't but about 30-40 hp. difference between all the aluminum heads out there right now.
run AFRs all the testing at work seem to be the best head for the small block.. i got ported 66 298 heads 52cc ones with 1:94 and 1:60s better then stock, cheap but not that great in flow... but my buddy ran 11:80s with a set. maybe it was the 5:12 gear he had in it that helped too...lol also ran first gen world product SR heads..2:02 and 1:60 not impressed... got roush 200s too..which are world heads as well... ok for what they are as they come with the crate however ROUSH just changed all crates to AFR now.... kinda tells you something don't you think. also have Trick Flows - Twisted Wedge.. 2:02 and 1:60 ported great head on stock 5.0s with a 303 cam as long as you don't any light lift then that and you might have some clearance problems.. but not a bad head at all. my friend also had this head on a 91 mustang with the following 3:73 gears, short shifter, underdrive pulleys, GT 40 intake with the upgraded air mass and the Twisteds right out of the box ran 12:80's every car is differant so its stil hard to say... but if i'd change i'd go with the AFR's
I wonder if my 347 CHP pistons will clear the 2.02 valves in an afr or TW head. I am leaning a little more towards afrs just because of price. I don't want to have to tear down my short block so I need to find out what will clear my pistons. I am running a .510 lift cam so does anybody know if the pistons will clear an afr or TW head?
If coast highs technical advice is as good as their customer service I got then I am sure it will be crap. I have an extra piston around somewhere. Maybe I can measure the valve reliefs.
Interesting post. I am at a crossroads as to what head to put on my car. I have been leaning towards the AFR heads. Now I am leaning further. My real deal is, I want my car to get down into the 12's... I am a full second and some change from doing that. But,,, My car currently has 78 302 heads that have been worked over. They were pretty decent when the motor was built but now they are certainly antiquated. I need an enclosed trailer as well. So many needs, too little money! Dan
I would have to vote with the AFR 185's (HC chamber) with upgraded springs (in case you want to up the cam later on) - mainly because they're the only ones I can comment on. I had a set of Windsor Juniors on my 347 and was really amazed at the increase in performance when I bolted the AFR's on. Check with AFR about clearance issues and recommended spring rates (according to your cam specs). Also, I'd ask about which cc chamber is good for your app. Pump gas? Race gas? Blower? Nitrous, etc. I actually see some people selling used sets - after they've totaled their car or are in desperate need of cash. I'd check a lot of Mustang (Fox Body) forums. Even go as far as put a WTB in the classifieds. Good luck, Rick
You might take a look at www.powerheads.com. They have late CNC ported E7 heads that flows a gang of air for well under $900 complete. There is another source for less and one for close to $1000 if your interested.
http://www.carcraft.com/techarticles/116_0307_ford/index.html good link above tech article from carcraft 400 HP With A Stock Cam! Totally Naturally Aspirated, And The Only Things We'll Change Are The Heads, Headers, And Rocker Arms AFR 165cc Heads so good in fact, that they are worth about 100 hp over a set of stock 5.0L Mustang heads on their own i like my AFR 185s they was a little over $1.800 with upgrades and shipping took some time to get after i ordered but well worth the wait I called some places that had them in stock but they wanted more for the CNC ports, found out that AFR sales bear castings and that is what some places sale you for $1,300 bucks and they have who’s knows what valves and there not CNC ported you can upgrade to the CNC, and hears wear it gets good they tell you it will take more time that the CNC are not in stock, they order the heads and have them drop shipped to your door from AFR you pay more and still have the same wait time unless you don't want the CNC
I'm really happy with my TFS track heats. I paid $825 (incl. shipping) for a set with about 2000 miles of driving on them. I guess i just got a good deal on them, but i'm really happy with them. AFR's are probably a little better (or a lot better, depending on how big of a port version you buy), but for my money i'm very pleased. My girlfriend got her TFS twisted wedge heads for $950 on sale (new). The reason i chose the track heats over the AFR's is money, mostly (new they are about $300 cheaper), and also i have heard good things about porting them--total engine airflow is one company that claims they can port them to outflow even AFR's. Either way, i'm happy and they get my recommendation.
I prefer edelbrock. If you are a real man, put a set of Victor heads on it. Not the jr's, just Victor.
