I have the problem with Stage V heads and covers. I used option #2 but was not quite agressive enough on the cut.,
#3 is the one that gets my attention. They were not available when i put mine in.
#1 is my least favorite because, even though you have a six pak hood, you could easly get into to T Bar/ header issues. Especialy with TTIs. You will also cause the back of the trans to hang lower than you want. Drive line issues will appear. You can even have these problems with the stock schumaker mounts as i understand they raise the engine.
