Default 302 Aluminum Heads Please Help

Ok so i have a 90' Notchback 5.0 w/ AOD. I am looking to get a set of aluminum heads fairly soon. Dont care about gas milage im looking for all out performance. Would like to keep the price around $800-$900. Ive seen the Patriot 185 heads. There are also heads on ebay such as Pro Comp. Which heads would be a better investment? Or should i look for a set of Edelbrock heads. 2.05 or 2.02 intake valve? What size imtake runner? I have an E cam with forged flat tops, underdrive pullys, no a/c or ps. 3.73 gear. Going to switch to carb soon also.

if you're running flat top pistons i think the only heads you can run without fly cut is the TF TW heads. anything else you'd need to flycut your pistons for clearance. I've seen one horror story plus pics of the patriot heads and its very sub par milling on these things. pro comps flow worse than stock so F those things.
stay between 165-185. neevr buy used heads either unless its gt40s. I'd say hit up the TF Th if you dont want to fly cut or grab up a pair of GT40s and get them worked over.

My buddy and i just installed a set of Edelbrock Performers on his 302. Stock pistons. He picked them up used for $500. So far we havnt had any problems with them. Which GT40's would be good? Preferably aluminum. And will they be sufficiant for a 331?

go to the junk yard and ask them to point you to the 97+ explorer 5.0's find one with the GT-40p heads and intakes, grab them cheap! clean the up re work them port and use them they rock.. i paid $400 for a complete running 5.0 out of a 97 exploder. check the heads for marks though 3 marks is GT-40 and 4 marks is GT-40p also it will say GT_40p on the front of head before the first sparkplugyou want to try to get the P's but both are good

Well the only problem i see with the GT40p heads is that you have to have special headers and ive only found shortys. I was planning on going with MAC full lenghts for an auto with 3" collectors. And are those still iron heads?

Save more money and by better heads. With stock pistons I would recommend Trick Flow Twist Wedge. As for the Patriots, they are complete junk.

Well im tryin to keep things cheap for now. So if i get the GT40ps will i be able to run MAC full lengths? Ive heard of people using headers other than the ford racing ones. What has to be done to make other headers work?

You get what you pay for, they are cheap for a reason. It is cheaper in the long run to do it right once.

well i wouldnt buy a set of assembled heads from ANY company if i was really gonna do it *right*...... so as long as the actual cores / castings are OK then it would be cheaper to get a bare set of patriots, work them over, and assemble with quality parts like ferrea valves and comp/crane/isky/crower springs

Most people do not have the know how or the proper tools to measure and assemble there own heads.And they will still need to go to the machine shop for a valve job to match the seats to the selected valve.You can buy assebled heads specific to the appliation if you are buying from the right people. I know Camshaft Innovations does this andthere are others aswell who dealwith camshafts and heads.

The problem with the Patriot's is not only the parts they use, therehasbeen notedmachining issues in the castings.

i guess it pays to be a machinist and have friends with machine shops[8D]

seriously, like i dont ever think about these things like they could ever present a problem. last week or so i needed to do a vavle job on a 1.3 L SOHC suzuki so i just brought it over to my buddys and gave him a 350 4 bolt main core i had in the garage in exchange for him letting me use his equip [8D]

Well ive been reading numerous threads on here for hours trying to come up with set up. I dont want shorty headers so i think im guna go with the regular GT40's. The ones that came on the early model V8 explorers. Then ill have those ported out like crazy. Whats the valve sizes stock on those? What kind of power can i expect from a fully ported set of GT40's? Plus it helps that my uncle owns a head machine shop so i can get them done fairly cheap.

Ive also seen thumpers E7 heads. It seems like he knows what he is doing. I just cant see an E7 head good enough to run 12s on motor with an E cam.

Thumper GT-40/40P's are even nicer and you can not beat his porting prices. www.thumperoforangepark.com

The heads that came on early Explorers are the GT-40P heads!(Have weird sparkplug angle, requires special headers)
P stands for production, Regular GT-40 heads were NEVER installed on explorers!
My '83 GT ran 12.831@104.44 with D8OE heads,( late 70's vintage junk, FREE)home gasket matched/pocket ported.
Milled .045" for compression and sized for 1.84" Int + 1.54" Exh. valves.
650 Holley, EDEL. Torquer 2 Int.,1" open carbspacer,.448" Int @204 Deg.472" exh@ 214Deg cam. 11/2" longtubes into 21/4" dual exh. 9x28" MT slicks and a 4.56 gear.
You don't need aftermarket heads if you keep the weight low and optimize your chassis.
Think NHRA Stock Eliminator type mods.Those guys regularly run in the 11's with minimal mods to the motor and a highly refined combination. AKA lots of test and tune!YEAHHHH!
