i have been looking into COMPcams cc503. Now, to go along with it i have decided to go with Crane Cams #270-10308-1 for the springs. Should i stick to the same brand for the pushrods and rocker arms??
its a 94 z28 a4 you can see that below.

 

The engine doesn't know a brand name. Trend makes pushrods for Comp and many others so don't worry about that. Just get some decent ones and not the pressed ball stock looking ones. Don't use cheapo rockers like the Procomp/Proform/noname brand as the trunions and bearings are not up to par. In your application though any name brand like Comp or Crane or Scorpion narrow bodied rockers will work great.

 

i couldnt find a set of crane pushrods... those are what i would like, are there ones from maybe an LS that will fit?

 

Since Crane is now out of business you may have problems finding those. I would just go with Comp or Trick-Flow push rods as they will give ya what you're looking for...
