header bolts

well today i went to ace hardware and got me some stainless allen head bolts and let me tell you guys i will never go back to the hex head bolts for headers. these bad boys went right in and tightend up great and since they are stainless i dont have to worry about rust or any other effects of oxidation i would reccomend them to any one else who is having this problem the ones i got for my x heads were 5/16 and 3/4 long. thanks guys for all the help its people like you guys that make me like this site so well
