When you change the heads out on a 98 to say anything 99 and above. Where has everone been getting the center bolt valve covers and the coil brackets at? Do I have to change out the coils to newer models or just change the brackets?

I got my cover and brackets from my GM local dealer. You can use the 1998 coil packs, just be sure you mount them in their corresponding firing order.
