How much is too much lift for Cathedral port heads.

I am back on the LS swap bandwagon, and have a few questions.

When my TH700r4 died. I knew it killed my 383 LT1's thrust bearing. Well it wore quite the groove in the crank. While staying with a carbuerates 383 LT1 was fine when it was a cheap rebuild. It is now not so much with needing a new crank. Plus controls for the 4L80E I have too. The 350 in my truck is for my Camaro so it is not a waste. As the 383's plan was a rebuild, and back in the truck.

I plan to run home ported cathedral ports, cleaned up tbss intake, and a 230 duration cam roughly.

With 600 lift cams being everywhere, and after watch Richard Holdner on YouTube nursing a knee injury again. Are they a good choice for DD? Or should I stay safe and get around a 550 lift. Or are today's springs good enough for 100,000 mile reliability.
