What do you guys think about switching to allen head bolts?

In the process of doing this now.

I actually modified a #2 3/8" drive phillips head (craftsman) to work on the stock phillips head screws. The only one still fighting me is the filter screen at the bottom of the engine (oil pan removed) and that's because I can't really get enough pressure on it to keep the head in place.

Modified = ground the pointy tip down by about 3.5mm so that it sits flat and engages deeper.

When all else fails... I bust out the grinder or cutting wheel.
