Just get a set of E-7 heads from a 5.0 EFI truck and call it a day.That's an upgrade from what you have,and cheap.The old 351 heads are good,but it's easier to get a set of GT40 heads.The EFI 5.8 heads are the E-7 heads like on the 5.0,but the holes for the head bolts are larger and you'd have to have inserts to use them on a 5.0 to make the the holes smaller for the 5.0 head bolts.

Why does almost everyone keep yelping about the E7 heads for pre '86 engines??? The heads on a '84 are similar to the E7s, you might gain 5hp, not worth your trouble... Major issue is the asthmatic CFI(throttle body fuel injection), and soda straw exhaust system... Just changing heads only opens up the middle of the airflow, still have a cork at either end...IF you could find the parts for the HO CFI system('84 '85 Mustang, LSC, and a very few small LTDs, with a dual exhaust system you could up the HP to something like 175... Maybe if you got the parts for cheap, but A carb or SEFI conversion is about the only thing that will really help(along with the free flowing exhaust system)...

Forget E7 heads unless they are on the car when you buy them or you buy a block with them on there. Go get some GT-40P heads or really start saving up and get ready to spend about $1,200 or so unless you find a used set of some good heads for sale.

The E7 heads did not see production till the '87 models... Sooo, unless someone has swapped heads, you don't have them or the E6 that were used on all passenger car engines in '86 through '91 on the standard output 5.0(HO engines used these heads in '86 and on LSC Lincolns in '87)... E6 heads were only used on SEFI engines(no trucks), so again unless yours were swapped you don't have those either... Heads used in '85 back to '78 are similar to the '87 up E7... Combustion chamber size varies, with the '78 to prob '84 having larger chambers that reduce compression a little as compared to most of the heads from '85 up...

BTW ID is generally on the non-machined area that faces the lifter valley... Unless you pull the intake and use a mirror you, can't tell... As long as your engine uses short reach spark plugs(1/2"), you have a fairly decent head(referring to factory stock pieces)... ALL factory heads used in the '80s, are junk compared to GT-40 or similar that were used on some(few) engines in the '90s... Aftermarket aluminum heads are  so far out in front of the factory pieces, they don't even compare...

May I add a question to this?

Is there any problems with aluminum heads on a 302 like the V6s.
or is it a V6 problem with head gaskets?

The only reason I bring up the E7 heads is because they are super cheap when you're on a budget,and most of the people are.I have the ported e-7 heads and like them.Once the new engine is built,I'll probably go with GT40 heads,or,if I can get the funds,aluminum heads.

Hey Daminc,the only problem I had with the 3.8 engine were the head gaskets.Ford made better replacement gaskets to prevent them from blowing.

Mine had been done 30,000 miles ago back in 96. Never had another problem since. But now the main bearings are clunking and I got no oil pressure after it warms up. now you know why I'm collecting parts. otherwise I'd keep the 6 in it

I haven't tore into it yet, but my 1985 F150 has EFI, and I've thought about what those heads would do for a 74 truck 302.  Along with the efi intake swap.
