AntiFreeze on the Intake?

Went down to the Swimming Hole this afternoon...
Smelled Antifreeze when I got back, thought that was strange after a fresh Top-end.
It was sitting near one of the small 5/16" intake bolts by the Choke Assy on a 273.
I used Thread Sealant (the White stuff) on all of those bolts and Copper Coat on the Intake Gaskets.
It's been good for 3 or 4 months.
Can I pull that One bolt out, Re-Seal it and drop it back in with any success?
