stinking water neck driving me crazy

yes, 87 bronco with a 351 in it
i did some reading on ford sites as well and next time it goes together, i will run a rubber band through the thermostat, and loop it aroun pencil or something to keep it in place
I use Permatex's "Right Stuff" on everything and never have issues.
I thought I'd at least get a polite "touche" for my first comment....
