Head bolt help

[Tom87GNX]

I'm not sure of what head bolts I need for my build. I'm thinking in need ARP 123-3601. I'm running a 1985 turbo block and stock 8445 heads. Will these bolts work? If not does anyone know what bolts I need? Thanks

thats the correct hex head bolts ,
my personal preference on bolts is the 12pt head (takes a 1/2" 12pt socket)
for your application in 12pt thats the 123-3701

Thank you for the info, yea I think I like 12pt better as well.

Why is 12 pt better? I've used both over the last 25 years and have not seen any gain at all. What am I missing?

my socket for 12pt clears the header better for retorques
