How many and how long bolts for exhaust ?

I am going to order some header bolts for my 350 and I want to know what the size is or was of the stock bolts. I believe I need 14 bolts and the size of them vary.

Thank you

Thanks guys. I ended up going with Stage 8 Locking Header Bolt kit with 1" Bolts. The kit I got was 8912A. This set comes with 16 in the pack (I needed 14 for my engine)
