I would not run "unknown valve springs" Buy the springs to match the cam.I also would run a high pressure oil pump and Milodon center sump 7 1/2 oil pan.
X2, look at some of the lunati voodoo series cams, they have kits with cam, lifters, springs, retainers, locks, and timing chain and are pretty affordable, i know alot of guys say lunati makes good cams, i know im gonna run one in my 440 build, be worth it to check them out anyway
