I would do some search and asking questions over on the LS1Tech Forums

One of the design parameters of the Morel lifters was the ability to handle higher lift without oiling issues. I would personally look at Morel lifters for this application. There are many of other improvements as well, this is just one.

I wouldn't be reving mine above 6500. I don't race it so maybe this is the way to go. I would hate to spend allot extra for the morels if the LS7 lifters would a reliable option.

Best to call a speed shop and ask them. Most vendors are aware of these questions and are reliable for the best answers.

I run the Caddy Racing lifters with a 610 lift and run pretty hard to 6850 rpm. ZERO issues (knock on wood) I also have the melling high pressure pump.
My buddy warlock007 switched to a set of linked lifters and is very happy with them. I forget who makes them.

My LS7 lifters did not make it but about 100 miles - but believe it is just a mix of a moronic engine builder and a factory defect.
I am upgrading to Lunati lifters just to be sure. They have the crossbar between them (linked lifters as said above). They are $375 at Summit.
