comp cam kit for 383

hey guys anyone use the comp cam kit for a 383? it comes with cam, lifters, valve springs, retainers, timming chain and sprockets and valve seals. the cam i would prefer is the stock 68 383 Roadrunner cam from MP. but the comp cam is similar and comes with almost all the parts i will need but i am not sure what grade the comp springs and timming chain that comes in the kit. I am on a tight budjet with this build. Thanks
