Tech Question - Big turbo inlet plenum bolts?

[Dan Le Moignan]

Hi guys, I want to order some stainless bolts for my inlet plenum to match the cam cover bolts I plan to use on my resto.
Please could someone tell me which type of bolts they are as standard?. I can't remember off hand if they were Allen head/ hex/ button head etc!
The sizes I have a note of are 6x m6x40mm, 2x m6x50mm and 2x m6x60mm

Thankyou for any help,
Dan

If you want them to look like cam cover ones than use allen heads. I used 12.9 allens with nordlocks under them to be sure that they are strong enogh and they ll not get loose. After I mached the sizes to the inlet as it has its own threats and you dont need nuts i zinc plated then and they look the bussines.
