To raise my motor a few inches on pass side, to get to spark plugs, do I remove the one long bolt on the motor mount, or the 3 little bolts to the block ?

Damn my big fat hands,, where is Jenny Craig.,

 

Usually just the one long one, but I know a couple of guys that say the bolts on the block are easier to get to. I would just do the one myself then put it back in the opposite way so it would be easier the next time.

 

I had no problem getting to the longer bolts. 1 on each side.

 

Forgive my stupidity, how do you push it out ?

 

This is how I do it, get the jack set up on the bell housing and start to lift it slightly to relieve the pressure/bind on the long bolt and push/pull it out easily. It should be that easy for you also.
That is what you were asking right?
