What cams are you planning to run and (thus) what is your dynamic compression ratio? If you run a decent amount of overlap + lift your DCR will probably be more like 7.5:1 (approaching ~8 at higher RPMs) and thus plenty of margin.
Thanks for the comment, I appreciate it!

I'm using the DC43x-102 cams from John Dougherty. I should be okay, but I am paranoid of the dreaded "ping" of detonation.

I am learning a lot as I am following along, thanks for sharing your journey with us. I have an engine rebuild coming up myself and the note file with tips and tricks is getting longer and longer.

Cheers from Austria,
Lukas
Thanks for the comment, I appreciate it!

There's no way I would be able to undertake this project without:
  • The collective wisdom of this forum
  • Wayne's How to Rebuild and Modify your Porsche 911 Engine
  • Bruce Anderson's Porsche 911 Performance Handbook

Tony's engine rebuilding class...

So getting the engines, equipment, tools, etc. would require some serious logistic undertaking.

I have a two-car garage/carport soon to be a 3-car parking space. If I park my ‘78 and ‘89 at my son’s residence which is only 7 miles away, there would be ample room to accommodate a small group (5 or less) for engine tear down or engine assembly class...

And especially Kurt at Klassik Automotive Training School. Kurt covers almost everything in the rebuild process and shows how to do things not covered by any book https://www.youtube.com/@klassikats.

Thanks for the comment, I appreciate it!

I agree with you and the pump was 30% off when I bought it. And, I wanted to have a pump capable of working with a front mounted oil tank and dual oil coolers if I decide to go that route at some point.
