im planning on throwing my mustang in storage for the winter, means i dont have to throw down cash on her every week now..but while its in there i plan on ordering a new set of heads for it..which of the following is my best bet (brand) for new heads???

trick flow
AFR
edelbrock
ford racing
dart
or something else..

im thinking aluminum, but what would be my best set-up for say a $1500 budget on these..

[Drick]

AFR FTW

[jam77]

yeah i agree thats what im going with

[Speedstang302]

"FTW"??? whats that mean? and thats what im kinda pushing towards, i had an 88 notch that i ran perfromer rpm heads on it and i liked em, but i also trust those other brands, but i've heard best bout AFR..

[HMUSN]

"for the win" it's just internet lingo.

[Iownastang]

AFR 165 if your gonna use stock pistons b/c of the 1.94 intake valve.These are very nice heads for the street.

[Tony_90fox]

Trick flow, AFR, edelbrock...All very good heads, i have experience with none so i cannot say which is the best.

[88dragstang]

TWISTED WEDGE BABY!!!!!!!!

I don't think you'd notice a difference between AFR, Edelbrock, or TFS on a mild street application. Edelbrock and AFR are the most straightforward to install. TFS heads may require custom pistons for valve clearance depending on your application.

There are alot of good heads on the market. I'd be willing to bet that the majority of people in this thread (or on the internet in general) that give an opinion on which head is the best have no experience with any of them or they have owned one set of good heads and think that brand is the best. Bad advice.

TFS twisted wedge heads are nice because they are the only heads that will allow you to use a 2.02 intake valve with a stock 5 liter piston due to the rotated valve angles specific to the twisted wedge head. All other aftermarket heads require different pistons or valve relief modifications to run a 2.02 intake valve. Ford Racing, AFR, Edelbrock, Brodix and Canfield also make nice cylinder heads. No matter which one of the above mentioned heads you choose, you will surely notice and feel a noteable horsepower increase.

I believe piston/valve clearance depends much more on the duration and centerline of the cam you are using, but more directly, the benefits of a 2.02 intake valve are questionable for a typical street/strip engine. The greater flow potential of a 2.02 or larger valve isn't realized in low CID/moderate RPM engines, but the increased shrouding hurts power down low. Plus a heavier valve requires a stronger valve spring...

AFR for the lose..
very nice head but a bit pricey for the nice head
notch the pistons and get RHS, best head made. but get iron.
the so much better head will make up more then enough for the added weight.

What type of proof do you have that this iron head will outperform any of the previously mentioned aluminum heads. The mere fact that any of the above mentioned aluminum heads will give you an advantage from sure loose of weight over an iron headed car.

I have used both TFS track heat heads and AFR 165s and can tell you this, both are good heads and if matched with the proper combination of parts will put a grin on your face from ear to ear.

Make your decision on what you need for your combo not from listening to people tell you what head they prefer. Like Darrell said some of these peeps have no exp. with any of these heads.

well remember im 18yrs old..so i'll take what i can get..im running F303 cam, harland sharp 1.6 roller rockers and comp cams double valve springs rated to like .600" lift or somewhat close to that..what is my best set up for heads with that????

Appearantly you are not familiar with the Twisted Wedge design. Valve angle has an effect on piston to valve clearance an in this case, like I previously mentioned makes the Twisted Wedge head the only head on the market with a 2.02 valve that clears stock pistons.

A 2.02 valve doesn't care if it is in a street engine. Being a street engine has nothing to do with what size valves are needed. A 2.02 valve isn't big anyway. A 2.02 valve doesn't need a stronger valve spring than a 1.90 or 1.94 valve either. The weight difference is marginal.

Please give me your definition of valve shrouding because your comment about shrouding doesn't make any sense at all.

[Tony_90fox]

I believe AFR's are pricey because they come out of the box fully CNC'ed...

I have read arguments on the web in which people dont know whether to spend the extra dough on the AFR heads or get a set of Vic Jr's (or a similar head) and then get them ported or CNC'ed...

But like Darrell said, alot of people just want to toot one brand's horn or dont have experience with aftermarket cylinder heads...

The only heads i have personal experience with on my application are E7's and ported Gt40 heads, so i cannot say what particular brand is the best or which is going to benefit you the most, but i do know the popular brands...

Again, the TFS Twisted Wedge does allow you to use a 2.02 valve with stock pistons, which i find a great feature! Just dont have the skrilla yet to buy.

[Speedstang302]

yeah well after hearing that im just, well not "JUST" gunna go with a set of trick flow twisted wedge aluminums..that sounds the best, cuz i'd like to run 2.02" valves and if i dont have to fly cut pistons..AWESOME..i dont wanna do machine work until next summer when i do up the 347ci..thanks..

You will be happy with Twisted Wedge heads. A few years ago I made 334 horsepower at the wheels with out of the box Twisted Wedge heads on a 5 liter with a mild hydraulic roller. Trick Flow makes a good cylinder head.

hey quick question, how much HP to the flywheel and Rear wheels am i maybe pushing with these engine mods..

ported upper and lower
heavily ported stock heads
1.6 rr's
f303 cam
comp double valve springs
manley stianless valves
65mm TB and EGR
73mm MAF
#24lb injectors
UD pullys
shortys
O/R h-pipe
super 44's
full msd ignition

Maybe 250 at the wheels with good air on a good day.
