Intake Pipe Bolts

[Rat44]

Is it normal for the screws holding the intake pipes to to Frozen in place?
I am going to replace the set on my 850 and I did not get far on removal.
The impact driver was not working.
I was just making a mess of the bolt heads.
I drenched them in PB Blaster and am hoping an overnight soak will help.
Any tips?

I forgot which one of the many resources mentioned this tip, but use Vice-Grips to turn the outer bolt. When that one is removed, turn the entire boot, it might grab the bolt and turn it loose. If not, it's at least an easier grip with the Vice-Grips to get on the inner bolt.

Visegrips was my backup plan.
I kinda' figured the bolts probably won't survive.
I am thinking about replacing them with Torx.
Allens have a habit of stripping out also.

RAT44 try this method. Take a 1/4" steel rod (preferablly high tensile) and 4-6" long. Using a club hammer (heavy head) place the rod on the screw head and hit from the side of the screw head. A decent screw driver might do the trick as well (though some here would not agree with hitting a screw driver with a hammer). The idea is to try and move the screw head side ways. Do this from as many angle as possible. You will probably only be able to get at the screw head from two or three sides. Ideally hitting it from four sides (12, 3, 6 and 9 o'clock).

Anyway see how you go.
