Default Valve cover clearance issues.

Putting my 84's engine back together to drop and and planned of using the stock valve covers I have powder coated and I found the roller rockers are just touching the side wall. The top has plenty of clearance just the pushrod side is tight. Anyone know a wider valve cover that works with scorpion rollers? I'm running Brodix Ik180 heads as well.

I have got these on my SBC. I think they make a center bolt one too if you need it.

Cheap, look good and seal just fine.

There are plenty of valve cover spacers. Perhaps that gives enough clearence.

Height is not the issue. I don’t know if spacers would space the rockets away from the side wall. The covers do seem to taper so maybe.
