You are right Jake. The first bolt I tried to get out is in there real good, so I was thinking I was going to strip it from not having the right size bit. But they are t-40 torx - I've got some out now. Thanks guys
Get the hex head ones. Be sure to seal the threads when you reinstall or you will get oil seepage on some.
I know that when running certain aftermarket runners, the hex head bolts create a clearance problem with a couple of the runners. Runners won't seal against the intake because the head of the bolt interfers.
I don't replace the those bolts unless one of the torx openings or threads is damaged. I then track down button head, allen head bolts from ACE Hardware.
