10-20 secs should be OK to wait. Try cranking 5-6 times then wait couple minutes to be on the safe side, then crank again. Mine took 10 cranks easy after replacing the rockers, with fuel filter fully primed.

Well it started!
There was a small leak from injector 3 I didn't notice.
There is a lot of fuel on the valve cover from me cracking the injectors. I notice when I start it #4 injector spits the fuel on the manifold up. So I think I need seals.

Looks like you didn't change the fire rings for the injectors and you're looking compression. Idparts.com has them. Btw, those are one use "crush washers" and need replacement every time you remove injectors.
