Yes yella terra do, they say about 10rkw or so depending on mods
Yes they exist, although a bit hard to find on the YT website. Any rockers designed for offset valve heads (LQ4, L76, L98, LS3, L92) will work, but not much gain to had for the money.
Current mods: 22" chromies on the front, 15" stockies with whitewalls and spinnaz on the back. Stock front springs, SSSSSSSSSL rears, standard shocks all round. Painted fuse box cover. Gauges all over my bonnet in chrome caps. Massive exhaust sticker across rear window. Tinted brake lights. Front seat so far back I need to look out the rear window. Single 2" exhaust with twin 6" cannons. Chev badges. MACE 1.9:1 rockers. Pod filter, high-flow MAF, cleaned intake, stock pushrods. MACE Ghostcam. Electronic supercharger.
Why have you included LS2 in your heading as the LS2 (same as LS1 and LS6, cathedral ports and straight rockers) and L98 (rectangle ports and offset rockers) use different heads and rocker systems.
