Ok so plan on 30.00 or more for reamer.
 Now valve seat cutting tools, probably 250 or more..
But that could get you started..

I mean I'm going to have to take it to a professional, that's just the bottom line. I just didn't want to . I'm sure this won't be a reasonable amount of money to repair, just a bummer and demotivating in all honesty.

Is there any members on here you or anyone can recommend that I can send this to to get repaired?

I did a search for said member and pulled up no results. I'll try with the case sensitive letters maybe.

First off how many are bent ?  And did it bend taking it apart ? Dont think it ran like that.
 IS it a 650  ? If so I can sell a brand new head for the cost of replacing all guides. 650 use 2 different heads.
 Demotivating ? Well if someone bent them due to not following procedure or not having a manual, then it was unnecessary.
How did you get the valve spring off ?
 Where in Montana are you ?
If it is only one guide it will cist more to ship than to fix one.

Not sure how many are bent, I stopped after taking two out. Not sure if it bent taking it out. I followed procedure on taking the two that I did remove, no issues with the second one. I used a valve compression tool to remove the springs and all components, centered everything in the bottom of the valve itself and used the correct diameter to compress the spring, removed the lock pieces that hold all the bits in there and the removed the valve rubber boot. I'm in Livingston, Montana. I'll have to do the others today and see how many others are in this condition. Also it's a 550.

He has done 2 heads for me, and does amazing work. If you want to be sure it is done right, send him a message. If you want to try and do things yourself, that's fine but you'll end up spending a lot of money on tools you may not use much in the future (that's how I looked at it anyways)

I found him and sent a message. I am with you Davez134, buying tools that are spendy that I may not use much in the future is a bit foolish. Plus better to have a someone who has the proper tools and knowledge of they're doing tackle the task. I've also reached out to a couple shops in Minneapolis as I'll be going there in a month for a couple weeks to visit family and friends. I'll see what they have to say.

Just a quick update. I removed all the valves, springs, collars, and washers. The only one that needs attention is the exhaust side of cylinder four and perhaps the intake side on cylinder two (there was a bit of a bur on the valve stem) I sanded this down lightly and it slid right out.

Late to the party, but take it to a pro. Guides must be reamed, and seats cut to ensure they are true to the new guides. Seat width is crucial for long valve life.Installed valve height is important as well. When I was in the auto repair biz, we averaged one aircooled VW engine rebuild a week...worth the investment in valve tools. One head is not.

Keith you're fashionably late man! :) I do believe that you and the other members here that have voiced their thoughts are correct. Taking it to a professional is going to be the best outcome for my build. I appreciate your insight and comment. +1 for a fellow former VW lover and tinkerer.
