Installing new head on 602, help please..

[Fidens]

So I got the old head off and am ready to install the new one. I have a few questions:

1)I'd like to to clean up the head bolt holes w/ a bottom tap, what is the thread size of the head bolts? I can measure If I have to, but hopefully someone who already knows can save me the time.

2) Is it necessary to refill the timing chain tensioner with oil, or can I just re install?

3)Since the I'm installing a remanufactured head, it's completely "dry." My plan is to blow out the head, soak my tappets in oil for a few days, and oil the cam bearing surfaces. Does this sound right, or is it necessary to pre-oil other parts of the head?

4)Can I just reinstall my old cam bearing caps, on my new head? Or is the procedure more involved?

Thanks in advance!
