Did you pull the heads? On vortec heads you have to cut the guides to have anything over .460 lift. Also your press-in studs arnt going to like the pressure from those 918's. You dont have to cut the seats for the 918's but you will kill your seals in no time at all.
As for push rods stockers will work fine as long as you are not using guide plates. A cheap fix are 92-95 stock LT1 push rods as they are hardened.

And thanks for the feedback from everyone, it's greatly appreciated

No the guide bosses stick up too far, and need to be machined down on the L31 heads. The bottoms of the retainers will hit the seals. if i remember right with a 1.5 rocker that cam runs .49X .51X on lift. Its been a while but i ran it in one of my LT1 cars and loved it. One casting is worse then the other. I have a set of 906's and they had to take off a quite a bit to clear .500.
