Yes.
Is best tho to also make sure the all at the same time that the crank is TDC, just where TDC is compared to the timing indicator and balancer (put them on temp). Most people will also advise degreeing the cam to make sure it opperates at the times it is supposed to. If not, is a simple matter to adjust the advance/retard of the cam to get it dead on and account for any variance in either the referenced grind, dowel pin location, crank keyway location, anything that would throw off the cam to crank base reference.
