Also, I have purchased Henry's kit, are any of the products suitable for use on the factory Porsche 'black' cylinder base o-rings or are these only installed dry?
Thanks in advance.

We have used Dow 55 o-ring lubricant on every o-ring in the air-cooled 911 engine for over 15 years with zero failures do to deteriorating o-rings.
Every o-ring failure we've encountered all 3 of them (out of thousands) have been the result of errant installation. No one is perfect.
I endorse Dow 55 because it has proven to works flawlessly. No conjecture from an angry troll, just proven observation.
