Thread Compounds for Lycoming engines

Hi,

I am starting to install an 0-320 in my RV6 and cant find any writen info on recommended thread compounds.

What have folks been using as a thread compound on Lycoming & similar engines, e.g on CHT ports, AN fittings etc?

More important are there any No-no's.

Thanks

Not Lycoming, but the similar Vantage overhaul manual.
