what are the advantages or disadvantages between 1.6 and 1.72 rockers. i have a set of heads that have 1.72 SVO rockers on them. i pretty sure it has to do with the lift, but again what are the pros and cons. i know another dumb question but if you dont ask youll never know.

More valve lift across the seat-to-seat open-close duration of the camshaft.

Yep,
Multiply cam lobe lift by rocker arm ratio to get actual lift at the valve...

.500" lobe x 1.6 = ???
.500" lobe x 1.72 = ???
(I'll let you do the math... lol)
