Does any body know the diameter, thread, and length of the bolts used to secure the exhaust pipe flange to the head? Also, any advantage/disadvantage to using typical "hex" head vs. "allen" head bolts in this application?
Thank you

Also, can anyone tell me what year this engine was manufactured? Base on previous posts, I believe it is 1977?
Thanks for the help!
