If the engine has iron heads and press-in studs, then no, you don't need guide plates. If the engine has aluminum heads or iron heads with screw-in studs, then guide plates would be appropriate.
Does your 85 Chevy iroc-z 305TPI have a facotry roller cam?
No GM did not start putting roller cams in the small block Chevy until 1987. The easiest way to tell is by looking at the valve cover although not always a definitive answer since you can swap heads or even get an adapter. If it has center bolt valve covers it is most likely from an 87 and later GM car or truck and would have a roller cam.
