Don't let your valve covers dictate which rocker arms you use - that's just silly.

Stock covers will fit most rockers. You will just need to clearance the VC's under the supports (you'll see when you put them on).

After clearancing, you can fit almost any...I like the CC Promagnum 1.6 NSA rr's.

Those aren't mine actually, but I clearanced my covers the same way. I use a little file to deburr the cuts. I have not had any clearance issues with my CC 1.6 Promagnum NSA rr's.
