Torx/Triple Square clarified. i knew it wasn't a Torx b/c is has 12 points but didn't know the name so went forward to be corrected. And yes, any normal auto parts store will carry it.

-Issue, I hear 10mm and 12mm. Verification that it is in fact 12mm?
-For the bolts 12mm x 104-105mm
12mm x 119-120mm
12mm x 145-146mm (and I'll find the quantities for these)

Guide rail? Does this part have another name such as "tensioner rail?"

The process appears to be very strait forward, my remaining issues are-
- Is the head so heavy that 2 people cannot lift it peacefully?
- Is removing the hood in my best interest?
- I am definitely correct in thinking I should replace the head bolts?
- Definitely take the head to a machine shop?

Thanks for the help thus far. I believe I will wire the chain to the cam and mark it, then see what I am most comfortable with once the head is ready for removal.

And yes I will remove the head because, a knock after 30second-1 minute of driving and that when I get on the freeway the temp goes from 10 degrees to about 90 in half a mile. Still no water in the oil, and no oil in the coolant (though it is rather dirty) but it it never goes hotter than around 90 no matter how far or hard i drive.
