1.6 - 1.72 rockers - differences?

[srjs28]

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)

will an anderson n-41 cam work with the 1.72 rr's and (gt-40's)? i also heard he offers a n-21 for apps with more lift.

or would the n 41 cam be complimented better by 1.6 rr.
