Hi this is my first posting here so thought i would explain what i'm doing. I'm in the middle of rebuilding a 1959 394ci Olds engine, I'm a bit stuck at the moment as i got this engine in box's and have found some of the Head Bolts are missing, Can anyone tell me where i might be able to pick up a set ??? There are 18 bolts in all that comprise of 12 x ^2, 16 x 4.5", 8 x 2.375" all are 1/2"UNC Many thanks Steve.
