Wet Header Bolts?

Took all the bolts out and stuck a wire in the holes. All holes are dry holes. Thanks for the help.
That's what I thought. My machinist spent a lot of time porting mine, changed all prings etc. and doing a vavle job. Then i spent some time sanding outsides, and reassembled.
And was sure they were but ya never know, thet may have had a batch that were not.
Heres mine all dolled up
