What else besides bad syncros can cause grinds?
I never had grinds until i installed a short shifter. The shift linkage kept hitting the exhaust pipe. Once I put in my new header and lowered the piping a little, i started grinding in 3rd at high rpms. Could this be caused by a bad linkage or fork?

And you are sure that the time between one gear disengauging and the next engauging is the EXACT SAME now as it was before [with the OEM shifter]? The faster you shift, the less time the synchros have to change speed. The less time they have to do that, the more wear they see.
If you do change gears faster (since the short-throw is meant to do that), your tranny is seeing more wear.
The other thing is bad/low tranny fluid.

Besides bad syncros on the gears...
- worn ends on the shift forks
- worn syncro teeth on the shift rings
- worn tab on the shift piece
- worn tabs on the shift piece interlock
- and improperly shimmed thurst washers
These are usually the things that I see that cause grinds, and gears that pop out.

I would be willing to bet that this is the problem. A short shifter will tend to force a faster shift, which foces the synchros to work faster than they are capable of.
