I did this calculation a while ago.

It's actually:

.480"/1.6=.300" lobe lift .300"*1.7=.510" valve lift with 1.7-1 rockers.

But, yes, the B cam is a good place to start if you don't have emissions tests. If you need to pass smog, the E303 might be better and the extra lift with 1.7's will give you almost the same power as the B cam.

Either way, check your clearances like Howard said, it's always better safe than sorry.
