Zero issues with factory distributor and vacuum advance

Found this

NOTE: This head will need to be machined for clearance if used with a MSD Ready to Run distributor.

Need a question answered

I noticed the intake manifold bolt threads are open on these heads, drilled through

Should i use a sealant on my ARP Intake Bolts like Hylomar or Anti-Seize or ?

Dont want any oil puddles on valley pan

Also the Edelbrock / Fel Pro Blue Perma Torque Head Gaskets should bee installed dry correct ? And looking at these gaskets it shouldnt matter what side is up or down

Thanx Scott
