I got the best springs BTR has ...platinum double springs and titanium retainers. 400 # 660 lift rated.Just make sure and run double springs. Too many LS guys think beehive springs will take it. If one spring breaks it's over. You really need the spring pressure to keep the lobes from loosing contact. Plus if the outside spring goes you have the flat spring on the inside to keep the valve off the pistons. I've have had to repair damage from that mistake and it's ugly.

That's a ginormous camshaft. I wouldn't want to even try to tune it for drivability. Extracting HP and proper A/F ratio is easy to do with HP tuners. It's tuning for good drivability that gets tricky and very time consuming.Wimps...
