d3ve heads for 86 f350?
1986 F350 stock.
I have found D3VE heads locally for sale that were rebuilt (supposedly, haven't seen them yet). Are these any better than what i have?
I am planning on puttin Weiand 8012 intake, mild cam for towing, straight up timing set and possibly a new carb maybe headers too.
At the same time, i plan on removing my faulty air pumps and other related SMOG equipment as i am exempt where i live.
I dont plan on boring the block or anything as this motor doesnt burn oil or anything, just feels tired.

i picked up a barely used crane RV type cam and lifters and got the intake for $100 for everything, along with oil pan, water neck, spare tire carrier assembly. I am looking at a new 750 holley today that has never had gas in it, but was installed on a motor that never got put in for 2 years. I dont know if it will be too big, but i feel my stock carb is in need of rebuild.
So i can get those heads for CHEAP, i just wanted to make sure they'd be ok in my setup. If nothing else, just fresh ones over my heads with 130k.

750 Holley might do ok, but keep in mind that's a lot of weight and too much carb will actually kill your performance. On changing heads, first they're heavy, second, be prepared to probably break all or most of the exhaust manifold bolts, third, what kind of emission inspection does PA have? Will it still pass?

Unless they have been modified, for all intents and purposes they are the same thing as your E6 heads. so they are a direct replacement. no advantage other then 130k miles newer and definitely no disadvantage.

Technically, there is a 'visual' check supposed to happen for inspection. That never happens here.
The carb actually is a holly street avenger 670. I assume it's a double pumper as it has two inlets for fuel, elec choke, and vacuum secondaries. Thoughts?

I think a 670 CFM carb oughta work OK, if you're running an RV cam and fresh heads. If headers are in your budget, so much the better. If you have vacuum secondaries, then it's not a double-pumper...which is good. Heavy vehicles, especially with automatic transmissions, tend to like vac secondaries better. Vac secondaries open only as far as engine load (vacuum) dictates, where a double-pumper is a mechanical linkage and as the name implies, has two accelerator pumps. You can always play with the secondary springs on your carb to fine-tune how fast the secondaries open.
You don't have a gas cap test down there?

I'm not sure what you mean by gas cap inspection? I guess that means we dont' have it!
This carb has a diaphram that opens the secondaries, elec choke.
It does also have a fuel line that feeds each end of the carb. i thought that meand double pumper, maybe not? I dont know jack about carbs.
Thanks for the replies.
On a side note, Would headers be better for towing/daily driver than exhaust manifolds? I plan on putting no more than 4000 miles a year driving and 1500 of that towing heavy(6-10000 lbs). I tow a dump trailer and gooseneck livestock.
