Yes stock pushrod are fine. Yes stock type good long slot stamped steel rockers are fine.
Make sure the all the springs are shimed correctly. to 1.70". The 305 heads have deep exhaust spring seats that need
shims to compensate. get comp cams spring shim kit # 4753. ya it matters.

The lunati 73943 is a better spring than the comp 981 if you are willing.
Another really good spring choice is the Isky 235D (1.75" installed height)

Set the valve lash cold at .016 to .018 intake and .018-.020" exhaust. Its that easy.

You can get more intake valve lift by using a 1.6 ratio rocker on the intake side.
intake side only is best. Use the better springs for this. lengthen the pushrod slot in the head a bit, towards the rocker stud.
It would be nice if you drilled and roll pinned the rocker studs. it's easy to do and costs pennies to do. Screw in studs are not nessessary.

thats up to you.

This combo will work really really well.
