1952-59 Ford Headman header bolts

Are these bolts special or can I use standard hardware?
I was thinking of using the black allen bolts.

 

yes you can i used them on mine but i used the stainless steel ones

 

Used the stainless allen's also but with Permatex copper anti-seize on the threads

 

Antisieze on stainless is a must. That stuff galds like crazy.

 

12 point, reduced head SBC intake bolts will work real well.
