How high can I rev?

I'm building my trubo motor right now, and I've got some ITR valvesprings lying around.

If I put those in my B16A with B16A cams....how high can I safely set my rev limit? I know ITR is 8600 - but B16A cams have less lift, so can I rev higher than 8600?

With the stock b16a cams you should be able to rev to around 9000 rpm safely. The ITR springs are plenty stiff for the lift of the b16a cams to 9,000 without valve float.
