Yes. There should be no rust on any of those components. If they are rusty it is very likely the engine has suffered a head gasket failure an/or sever neglect. Also very likely there is rust in the cylinders.

While it doesn't look good, I've seen worse.
If you are going to rebuild it - don't worry about it. If you want to run it, make sure to replace the intake manifold shield as they are neede with EGR manifolds. Oil changes!!! Use an oil known for cleaning ability, like Penzoil Platinum, or research something else, then make sure you can run it up to temperature normally. I would run it a lot to get 1000 miles on it, then change the oil. Then maybe another 1000 and change the filter, cut it open and have a look. I would probably do three "short interval" oil changes no matter what that second filter looks like.
This looks like an engine that maybe didn't see much use or didn't get up to temperature often. Short trips are considered "severe duty" for a reason.
Good luck!

As far as I know the truck has been parked for at least 2 years, I will run it when I get the carb and gas tank and radiator in, I already changed the oil once and ran it for like 30-40 seconds to try and cycle through the oil. Good advice, would you try and clean the parts while still attached to the truck or would you just run it with cleaner oil or rebuild it?
Edit, are you talking about the intake gasket?
Edit2- does that look like the headgaskets have been damaged?

reebadoo,
Sorry for the delay. If you wanted to, it looks like the pushrods are especially rusty, and since they are relatively inexpensive - you could replace those. I don't think I'd try yo do any cleaning otherwise. Since you put fresh oil in, you could drain a little and add a quart of ATF. That stuff really does a good job of cleaning things up, but it will take quite a bit of time no matter what. Run the engine up to temp for a while and let it do it's thing. As for me - I'm an incurable gearhead, so if I had any reason to rebuild/improve it - I would! Too bad it gets expensive!
Yes, I was referring to the intake gasket.
No, I don't think it has had a head gasket failure.
Since you've got it a fair bit apart, you might consider buying a new double roller timing chain and installing it straight up. These engines had the cam installed with the timing retarded apparently and that helped the "boat anchor" reputation. Installing "straight up" is supposed to liven them up quite a bit. No personal experience there.... Just what I hear!

From what I understand I can interchange parts from any of the 335 engine family some easier than others. What I'm looking at because I already have an intake and quadrajet carb, and the valve covers are not off the engine at the moment I took those pictures last April or may.

All engines from that era were dogs! That's the truth!
The 400 is easy to improve that's for sure. Use early heads (same as 351C 2V), or some minor porting on the later heads, and you've got a good base for a "performance" truck engine.
What's the truck?

Pushrods are something that it doesn't hurt to get good quality ones. I'm running a set of COMP magnum pushrods and they are great.
If your not planning on a big cam or stiff springs, good quality "stock" pushrods will be fine. Such as these.

If you are gonna run a cam and high pressure springs, Or if your feeling spendy and want better

How are they? Will the "middle ground" rods hold up to stiffer springs and a better cam?
