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.
89 LX Coupe: Factory 5.0, common performance and suspension bolt-ons (306 build inprogress)
86 GT: (current 1/4 project) will have primarily Team Z suspension and chassis additions, 408 with nitrous in the works
2003 Mach 1: programer, exhaust, 4.10'
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?
