I need help fixing this cylinder head

one of the valve cover bolts snapped off and also 2 easy outs snapped off in there too, should I just drill this to a nice circle and tap it?:


Also this thing (sorry don't know what it's called) is bent as you can see, is that easy to replace? :

I would rather take this all to a shop but I really want to keep this as cheap as possible. please don't make fun of me lol I just want to do the right thing.

how old are the heads? how many miles are on them? I would take them to a shop and see what they can do with them. You will need a valve spring compressor to repair the part that sits on top of the spring, (I don't know what it is called either). If the heads have a lot of miles on them and you have them off the engine it probably wouldn't be a bad idea to take them to a shop for repair and have them do a valve job on them while they are there. Plus the shop probably has the part that sits on top of the spring just laying around that they would probably just give you if you have them do the work. Drilling through the easy out is probably out of the question unless you have a very nice and expensive drill bit. Also if you try and drill it and get crooked which you probably will because the drill bit won't want to drill through the easy out and a bit that small will just walk to one side of the easy out and just make a larger mess. If you want to do it right take it to a shop.

IMHO if you really don't have the means to do this repair it shouldn't cost to much to have a machine shop to fix it for you. JMO You should be able to drill that out and re-tap it and if the head is off it not a big job to replace the valve spring either if it's still on it could cause a problem if you have never done it before, JMO Again. Just how did you bend the top of the spring anyway ? I call that part of the valve spring the hat or shield .

I was putting the engine in without the valve covers on and the chains got tangled up with it and when I pulled it up it bent

My suggestion is leave it as it is. Use RVT sealant on the gasket and run it. I ran a head with a broken valve cover bolt for I don`t know how long and it never leaked a drop, and it was broken on the bottom side where oil pools up. Yours is broken on the top where it`s far less likely to leak. I use RVT blue glue and would coat the bottom of the gasket all the way across.
Since yours is on the top, use it on the area where the bolt is broken and on the corner of the valve cover. Bolt the valve cover back on and place a concrete block on top of it and let it sit overnight. The block will force the cover down and the glue will form a seal when it hardens.

I have seen this work when it was on the top as DV said. If it don't then you know what to do next.

I'm not going to make fun of you but I can laugh If there's anyone on here that hasn't had things go wrong, their lying! It's all part of the learning process.
Is that engine the one you were having problems getting to charge? did you get that fixed?

Blast it out with an Oxy-Acet torch (the broken bolt/easy out combo). And WHY do they call them "easy outs" when this sort of thing always seem to happen; they should call them easy-oh crap!, or something similar.

broken valve cover bolt

How can you drill it, if you broken 1 easy-out in it? If you got the out and you drilled hole is in the center, just drill it a little deeper until you get through the bolt then use a square easy-out and kind of work it left and right to get started backing out. Once you grilled through the old bolt it might re-leave some of the pressure on the bolt.

the first easy out i used the spiraled kind, broke that off. then I tried to get that one out using the squared kind of easy out and broke that one in there too lol. now the hole is covered with easy outs and the drill won't go through anything.
I'm starting to lean on towards a shop seeing as how I've only been making things worse
