If you got enough info, you could roughly calculate clearance and at least if you have a chance. Not sure if all this info. will be available.
1. The valve timing graphs for your stock cams and the GT2 ones. Both should be available. The grinder of the GT2 cam should be able to provide it for yours with the 107 lobe centers. These graphs will show lift at different crank positions, and will tell you how much different the lifts are at TDC +- 20 degrees, which is where piston to valve clearances are critical.
2. Not sure if you'll be able to find this as easily, but the valve to piston clearances for your stock cams in at TDC +- 20 degrees.

If you're able to come up wtih #2, you can calculate your clearances to at least know if you have a chance with the new cams.
