The question is simple. Will full roller rockers 1.6 fit the stock covers?
I hope so because i bought an extra pair [emoji6]

Some may. Some won't.
Depends on the size/shape of the rocker, the size/shape of the interior volume of the cover and the valve lift.
At one time, I owned a 400 cid Gen 1 SBV8 which had Crane, 1.6:1 gold race rockers under stock, sheet metal valve covers. Valve lift was modest.
In short, you're just going to have to try them. Use thick the valve cover gaskets with the steel reinforcments in them. I think FelPro makes them.
Bolt on the covers then turn the engine over by hand several rotations then remove the covers and check for marks. If you don't see any, put them back on and run the engine at idle for a short time. Pull the covers again and look for marks.
If you see no marks you're probably ok.

Thanks Hib!
As I'm also going with a modest cam I can give it a try.

Peter,
of course, there is always,"cheating". Depending on the geometry and all that, perhaps a thick gasket could help. I bought some thick valve cover gaskets that are about shy of a 1/4". However, I have standard 1.52 rockers with roller tips. Needless to say, it would involve experimenting.
