Cam cover bolts type

[e635815]

It is a lovely sunny warm Sunday and I am getting ready for the camshaft change this winter.
But right now I am stuck by those cam cover bolts.
The have a star patterned head similar to torx but with more points and about 8mm diameter.
I don't have such a tool and none of the standard nuts will go.
Can someone enlighten me as to what reference shall I order and what's the name of that nut?
Thank you all.
Regards
Philippe

Firstly, it's rocker covers but that's just me being pedantic. The tool is a standard 8mm dual hex socket. They are sold by the usual TVR parts places and I've seen them pop up on ebay. It's a difficult space so the special tool is very helpful

Nothing bad being pedantic from time to time
Double hex was the information I was missing.....
Let's hit the garage again....
