Thank you all for your insight. I was not aware of oil leak problems with boring out the case. I asked a reputable Porsche machine shop located in Santa Ana about boring out the case and they said the case could be bored out to 3.8L without any problems. I guess I did not ask the right question about cylinder sealing issues.

I do not like oil leaks and IMHO oil leaks are a sign of a poor rebuild.

I may just keep my stop P/C since they have about 2K on new rings and
I have excellent leak down

Investing in a stronger stroked crank with upgraded rods now makes more sense. I have a few more questions if you don't mind

1. What hardware do I need to get the 964/993 stroked crank to match the internals of my case?

2. Do I need to perform any special work on my existing stock 3.3L P/C so they will still seal with this new longer stroke?

I'm also going to have the heads twin-plugged for future upgrades when I finally do EFI.

Thanks for you help.
