VALVE CLEARANCE

ok, with all the rocker talk lately. it has me wondering if, I did put a set of 1.6's in my slant.
would I have enough valve clearance? cam is currently a 465 lift, would end up 496 with a 1.6 rocker. head was only given a slight shave, block on the other hand was given a bigger cut.
we cut .120 off the block. pistons were still a good .030-.060 in the hole ( if I remember correctly ) just wondering if I would have to pull the head to check the clearance or ?
