And as it goes - if you want clearance then you want near stock height valve covers. That points towards steel rockers. The Crane units that were OE on the 93 Cobra test out at 1.72:1. They are relatively light and very strong. Unless you are building a very high dollar screamer there is little reason to use aluminum when you look at the reduced longevity and greater flex.
If you are not right at the limits on your valve springs there is a good chance you'll see more power with steel rockers and all other things exactly the same vs aluminum just because of the way it flexes under load and this flex increases with heat.
Id look at a roller tip steel rocker set personally. It's just simpler to sort out.
