Max lift has nothing to do with ptv, valve events are the most important part. you should be fine with the N41 but when in doubt clay it. what springs you using ( you didn't offer any other info), coil bind is something to consider also.
to get total vlave lift multiply lobe lift by rocker ratio. you can get lobe lift by dividing cam lift by rocker ratio.
Example:
.480/1.7= .282 Lobe lift .282 x 1.6= .451 valvle lift
.480/1.6= .300 Lobe lift .300 x 1.7= .510 valve lift
the numbers I just gave would be spot on for the "B" cam
