Wisconsin head bolts

When any of you guys have put a head back on a Wisconsin have any of you ever used never seize? I have ran a tap down all the holes in the VH4 I am still messing with. Have bought all new head bolts and the thought crossed my mind to put never seize on them. Is that a good idea or a bad one? Any thoughts?

I don't know the official line on this but mine will have never seize on the bolts. For me they can be real ornery to get out.

I do not believe never seize would have any bad effect on anything but wanted to get others opinion.
Thanks

anybody else have an educated opinion?

if you look in from top side of the jugs you can see some of the head bolts stuck thru the treads and can rust on ends these are the ones that brake all the time when you remove a head i use a litter shorter cap screw in place off them stops that trouble and yes use anti sizes these bolts are in the middle of the head between cyls

I would bet that one flat washer would be enough to keep the head bolt from sticking far enough out to rust. I know when you bolt things together you should have a minimum of a thread and a half maybe more beyond the nut. That might not apply here.

My Jan 85 VF4 manual says to use mixture of graphite and motor oil.

Sounds like they were or are aware of a problem removing head bolts without twisting them off. I wonder if never seize is an equivalent of the motor oil and graphite. I would guess the motor oil was used to make the graphite stick to the bolts. If their factory would have used something, us in the field would not have had to worry about twisting off head bolts. Those center three are impossible to get at with a torch. I can remember a bolt or two not feeling good when I started to take it out. I used the torch to heat the block area of threads and removed the bolt with no problem.

I think I might try the never seize. I don't think I will be the one removing these heads in the future.

I might try this. Have done this for bleeder screws on wheel cylinders and it works most of the time. Use my air impact and set at lowest setting and work up . It is better to go slow than fast.
Rattle on it for a minute or so . Might shake something loose.
