Sounds good.
What taste difference is there from a 90 minute boil than a 60 minute?

Longer boils tend to darken the wort and there are maillard reactions taking place producing more melanoidins that enhance the maltiness of the wort. Not to mention increased hop isomerization or enhanced hop bitterness. The longer boil also concentrates these flavors that are created during the boil. Driving off DMS is probably one of the biggest reasons to boil longer but these other attributes also come into play as well. Taken from a book!!!:whistle:

Would you do that with most beers or just specific types such as stouts and porters?

I would say specific types of beer require specific attention.

I probably would not boil a summer ale 90mins.
Also take for instance weissen beer that requires a 2 or 3 stage decoction to achieve the flavor profile.
 
So porters and stouts could go 90 minutes? I'm doing a coffee chocolate porter tomorrow so the timing is just right!!
 
I wonder if you taste the difference between a 60 minute boil and a 90 minute boil. My guess is no. You might achieve greater clarity is the the longer boil.
 
I've also read darker colour from longer boil which may be desirable in this style. Whether it's noticeable or not I don't know.
