Is this correct? distributor install…

I verified that i was at correct TDC, by looking through the exhaust port. When i turn the engine crankshaft about 90 degrees past TDC, the exhaust valve starts to open. I have the balancer mark right at the mark, and the distributor rotor pointing right at No. 1 cylinder.
Are these positions correct for initial install of the distributor?
