Where you have problems with the stock LS7 head is madhining the spring pockets for larger diameter springs normally associated with solid roller cams. There are springs you can run for a street solid roller that fit the stock spring pocket that will be safe.
...although "this guy hasnt had problems yet" isnt a very compelling argument when its only been done a month.

Where in the lift rang does it flow 400cfm? I have lsx-ls7 heads and they flow 400 at 650 but drop off after that. In my opinion solid roller is only necesary for 8000+ rpms or huge lift in the 700+ range.
But asside from that I would suggest in order Jesel, crower, morel then all others. I have also done a little but of research before about solid roller and it would be wise to open up the lifter bores, install bronze bushings and install larger solid roller lifters. The wheel on ls style lifters is a little small for prolonged use on solid roller pressures.

Isky EZ Roll. You don't need a solid roller to run those rpms with a Hyd Roller if you have Ti valves although there is some increased power potential with the solid. Morel are a good alternative and their HLT option could work very well for you with the right spring.

If you already dropped the dough on adjustable rockers I'd say go for it though.

If the engine isn't assembled I'd always go this route and install larger dia. lifter bushings if funds allow
Thanks for the feedback guys.

@ John B, I do not blame you building a bullet proof valvetrain, even shifting at low to mid 7000. I'm still building my engine and i'll only be shifting at 7800 to low 8000 with some big valves and my solid set up is over kill. But it's for my peace of mind...
