i reccomend Mr. Gasket ultra seals. dunno the part #, but i run em and don't have any problems. a good set of 1" header bolts should do fine. you could splurge for the stage 8 locking ones like i did. except, on my headers i couldn't use the locking tabs cause it won't fit over the head of the bolt because the tubes are in the way. so that was like $40 wasted, but they do hold good even with the locking part of it on.
