25 thousandths is a big enough difference in lift that you could measure it with a calipers or micrometer fairly easily.
Measure the base circle
Measure the tallest point of the lobe.
Subtract to find difference.
Multiply result by 1.7 (for rocker ratio) and find your gross valve lift.
It wont be EXTREMELY accurate, but it will get you close enough. As I said, .025" is a BIG difference and should be easily measurable with a standard caliper, etc.
