Aircooled engine/metallurgy question

[67R69S]

Hi Folks, I'm assembling this 73 year old aircooled engine and I'm trying to figure out what sealants to use. Would it be reasonable to use the same sealants that we use on our 911 engines? I'm not sure of the exact make up of the old aluminum alloy; am I over-thinking this whole thing?

Thanks for any advice, good-natured derision, etc.

Over thinking. And don't use asbestos gaskets...

If you ever need parts my neighbour is Bob the BMW guy, semi-famous the the local BMW crowd.
He owns an old school house and it's right full of BMW's and vintage bikes.

Three Bond. Thats all you need.

Otherwise known as Yamabond, Hondabond, etc..

I was going to suggest a couple fine must have Porsche books written by our own host...
But...
A brief search on this website using the terms "books"+"engine"+"101"+"wayne demsey" produces no results!!!!

WTF.

Thanks guys, I'll treat it as if it's a 911 engine, for which I happen to have the necessary sealants. A barn full of vintage bikes? How intriguing!

For VW engines, I've used Curil T and Locktite [something] as well as Aviation Permatex. For S&G, on my most recent motor, I used both Curil T and Permatex.

the Hondabond is called Hondabond 4 its a gray paste and made for sealing aluminum and other metals,
It stays semi soft once its cured
