Gt40 or E7 heads on a 331
Factory Gt40 Or E7 heads? Don't really want to put alot of money in either set of heads. Wanting to get a set of afr or something , but want to drive my stang now until I can save the money for the good heads. Had some bad luck over the winter while I was away at work. Long story short got rid of the pro comp heads and block is at machine shop being cleaned , checked for cracks, and re honed. I have a 331 with 3.25 eagle cast steel crank. 5.4 Eagle SIR I beam rods, Kieth Black Icon forged 331 pistons 54cc=10.3,58cc=9.8,64cc=9.1,69cc=8.7. A Weiand stealth intake, a trickflow stage 2 cam duration 224/232, lift 542/563, also have a tfs 1 cam 221/225, 490/510 laying around and some comp 987 valve springs. The trans is a c4 with a trans go shift kit, a PTC 3200 stall, and it has a B&M hammer shifter. All in a 87 gt. It's going to be a daily driver just to have a lil fun. Just need some advice on heads that would be good for now. Nitrous or turbo plans for later

dont even bother building a 331 if you only plan to use either of those sets of heads... people with h/c/i 302's will blow by you like you are in reverse.

why is it when u ask for help or advise on here and some people post just to talk S***? I know the flow of either head will hold me back. I will be getting heads in due time. Just not right. Probably will have the gt40 heads p&p , machined for comp cam 987 valve springs, and run the tfs 2 if no ptv issues.

i think the GT40s are better than the E7s, but i wouldnt even bother putting anymore work/ money into either of those..i would just put the Gt40s on and save for some nice aluminum heads.

Still no real answers. Dont need anyone to make me feel good about my combo. Just asked a lil input on a issue I am at now. Appreciate the input. But I know the heads are pos but I dont have the money to go out and buy a pair of aluminum heads right now. I know for 35-50 bucks I can get the gt40 heads machined for the 987 springs that I already have. Trust me I dont want to put any money in them. But tired of my car sitting. Would rather drive it know there is more hp and tq to gain once I do put a good pair of aluminum heads on
