Hey all. My LT1 heads are getting a set of 1.6 ratio Harland Sharp roller rockers with matching stud girdles and I need a set of valve covers that can clear them. Here's my options...

1. Stock covers - I'm guessing they won't clear the girdle

2. Canton fabricated aluminum covers - notched for the alternator but I'm unsure if they'll clear the girdle...

3. Composite LT4 cover - still, not sure if it'll clear the girdle...

Ideas?

 

The canton ones should work for anything, they are huge. I don't know for sure though, haven't done any upgrades under the valve covers.
