Well i just upgraded from the stock style starter to the high torque style starter and figured i would share my experience.
Here is a picture of the stock starter

After pulling the starter out i seen there is a huge difference, the aftermarket starter comes with a built in solonid that has to get a jumper wire to use with the remote mount solonoid. To clear my headers i had to rotate the mount but it was just 2 alen keys and no big deal. You do have to check pinion depth to make sure you have 1/16 clearence from the flywheel (i was fine) but if too close they do supply a ship to install.

here is a copy of the instruction sheet it says the starter is good to 12:1 compression
