I wouldn't worry about restrictors if you're going to do pushrod oiling only. Just plug the holes in the heads and roll on with it.
Are you sure that you have
oil coming out of the pushrods? Trend makes my pushrods for me and even when I request non-oiling pushrods, the ends look like they have holes in them....but they're actually plugged down in the tube.
As for the T&D rockers, you have to be careful about how you adjust the adjuster screws. There is a spot called the "initial adjuster position". You start out by backing the adjuster up in the rocker arm all the way. Then you turn it one full turn down and that's the initial position. You're not supposed to go more than one full turn in either direction from that position or you could possibly block
oil off to that rocker arm.
If you haven't seen a lapse in
oil pressure, I doubt you have done any damage.
Also, the end bolts on the rocker shafts need to be torqued. I'm just mentioning these things since you didn't have the instructions...
