Rocker arms/ valve springs

After reading about all of the different problems with cam issues.
I´m getting more worried about my configuration of the cam and rockers.
I´m using stock stamped steel rockers in my 383 with a Mopar Purple 284/484cam.
Have any of you guys been using the same set up.
The engine is in the car, have done the cam break in but haven´t had it on the road yet. So I figure it´s not too late.
Should I use adjustable rockers to avoid interference between the rocker arm and the valve spring?
Would it be enough to crank the engine by the hand to check for clearence?
