Rocker covers are attached, certainly in the case of my engine, with 4 screws, 1/4 UNC.

I cant remember as I always change them for allen cap screws but it definitely wont be metric. If 8mm is loose then it will be 1/4.

I think that's the thread 1/4 UNC not the spanner size your need.
5/16 would be right as that the closest to 8mm.
as other have said I always fit stainless cap heads.

No, it's exactly the same size as 7.93mm
The socket size that you need is 5/16" AF bihex. You'll find it's a tighter fit than an 8mm one.
