ive got a 93 lt1 and i have com cams full roller rockers and they dont look like they are gonna fit with my stock covers, and i know if i get tall covers they will interfere with my alternator, so im just wondering if they make a cover that will work or if there is a simple solution to this

 

i cut out the middle supports and breather on my stockers and they fit with comp pro-mags...

 

Do a "search", there are several posts and a couple writeups with pictures involving this. It is a simple fix, just requires some notching of the internals of the valve covers.
