sohc exhaust manifold bolt sizes, one more thing

[Tx-Sx-FS]

my manifold like several peoples is missing some bolts...what i need to know is the length, size, and any other information needed for replaceing missing parts...are they studs with nuts on the end or just bolts that screw into the block?? mainly need information for replacing to hold my turbo manifold on when i get done time this week also..will a 23.5x6.5x3 intercooler fit in the front bumper area without modifications? how will the piping be done with battery in the way if not going to move the battery to trunk?? Thanks in advance.
