Almost everything is an upgrade but the stock cam doesn't come close to maximizing the protential of the factory E7 heads and will be a bottleneck with better heads, so what is the big picture?
What are your plans for the truck and why are you needing heads?
it’s my daily driver and I broke some intake bilts off inside my heads. I feel I’m going to do the same when I take the manifolds off. Iv tried every trick in the book and couldntget em to break loose. I don’t think it’s ever been apart in 30 years

right now I’m looking at some edlebrock performers #60399. Nothing too crazy and not to pricey. I plan to get some new headers soon and in the future I’d like to change my cam and intake. I definitely don’t want to buy new injectors rn. I just got 8 new ones at 19lb/hr. They were pricey
edit: I really like the look of aluminum heads. I could get some rebuilt e7 heads or get the ones I already have drilled and tapped but they are all painted black and I’m not in the mood to polish them. Aluminum is lighter and the edlebrock ones come with a thread upgrade to get away from aluminum threads

You need to think about how much you're willing to spend on tuning capability if you want really good heads. Then the other things, like long tubes/exhaust mods associated with them, cam, intake manifold (the factory 351 lower intake is pretty bad to support mods) etc. If you plan to own this truck for another 5 or 10+ years, all of these mods are very worth it. If not, get a set of gt40 heads and port them, rock it, and dont look back.
Then he will have to spend a grand or 2 on heads, still
1. It is a long block.
2. I'm pretty sure this a cover-up question for his other thread where he messed up his heads and probably lifters by randomly tightening rockers then running the engine

Way too much head for stock block.
That will cost you about 7-1000. How do I know?, cause those are the heads I bought.
you will need to notch or get different pistons, 2.02 valves do not have the radial clearance, and will hit the piston.

Yes that is common. You could buy some remaned GT40s get an upgrade and not have valve clearance issues to worry about. Those with a small cam upgrade make a 300hp, that is the border line(actually slightly over) where larger injectors and tuning is needed.
