Shift Forks Set Screws are Stubborn...

[project74]

Any advice on getting the stubborn set screws to budge...I have tried heating the allen T-handle on the end and letting it sit in the set screw...but so for no luck on budging it....I'm afraid of doing dammage and then not being able to get it out....ANY TRICKS?

Are they rusted or just tight??
I recommend 50/50 acetone/ATF and a hammer impact with the proper allen in it.

I sawed off a straight section of allen wrench about an inch and a half (keeps the twist to a minimum) and used a socket that exactly fit the allen wrench. On the really stubborn screw, I cracked one socket, but the next one was a SNAP-ON and it held up. I got more torque with a ratchet than with a t-handle.
