Head gasket/valve job 103 engine

[J.HIDALGO]

Finally, I been putting this off for a while but, I think I am ready (I think) now to take a big jump and remove the head myself, in the next couple of weeks, and then send it to a machinist for a valve job.
I have the CD and read quite a few posts on this job. However, I need to double check on the parts needed. So far I came up with this list:
- Cylinder head gasket kit. Do I need all that or individual pieces?
- Cylinder head bolts X14? What size is the twelve point socket?
-Time chain tensioner. Necessary?
- Timing guide rail (inner). Maybe...
- Timing guide rail (outer). Maybe...
- Timing guide rail @ tensioner. Maybe...
- Bypass hose, since I am already there.
- Sealant front cover 002 989 73 20 10 (loctite5900)
- Sealant "U" gasket 001 989 89 20 10
- I know I need a 6 mm? bolt to extract the guide rail pin.

I already have the valve cover gasket. I am planning to leave the intake manifold in place. I have a good number of tools but, I am wondering if I need any "flex" sockets/extensions or any special tools.
Any tips an/or missing anything?
Thanks!
