.600 lift springs and .590 lift cam

Are to talking about valve spring retainer to valve guide clearance? Piston to valve clearance? The only way to know is to measure as all motors are different. Inner spring needs to be removed for break in with todays junk parts and oils. I learned that lesson the hard way. With cams this big I would measure everything possible. Degree the cam and measure all your clearances or you will be sorry.
