Valve Cover
 

I'm trying to find a set of valve covers that'll fit over my roller rockers, and eventually with stud girdles, and fit under my Edelbrock EFI intake with a 3/8" spacer. I've seen a bunch, such as the Ford Tall series, way too much money here, Comp Polymers, good price here, just told that they'll crack and can't be torqued down properly. Any ideas, I'd like to stay relatively low cost, but I'd like clearance, not so much looks. Any ideas?

You Must make sure it is for a EFI car when you get them.

I realize I need EFI covers, that's what I'm trying to find... Ones that'll clear my intake and fit over stud girdles and roller rockers.

Anyone have the Comp Polymers? If so, how do you like them?
