Well, a .530 lift cam will NOT fit.

If the "bottom most part of the retainer" is also lower than the lower most edge of the keepers; and the "top of the valve seal is representative of ALL the seals; then .600 less .030 =.570 lift, the suggested maximum lift. How you get there is up to you. That is to say what lobe lift to use will need to be back-calculated to allow for the rocker arm effective ratio and the lift-loss from the pushrod angle.
In light of the above; .525 valve lift seems pretty conservative, and .525 advertised yet more so, cuz the advertised is not likely to be the true. After the cam is in, and at least two rockers are mocked up, you can measure the actual lift and seal to retainer clearance and spring installed height,and then you can adjust the installed height to achieve whatever the cam guy wants it to be with the springs he says to use, and finally check for coil-bind.
And don't forget to adjust the pushrod length for lifter preload,and
to check the geometry, and
don't forget about piston to valve clearance!
lol
And if it was a hemi-headed motorcycle engine, you would also have check for valve-to-valve clearance.
lol
