make sure you torqued them down right? might need oversized headstuds.

you need to up your mainjet, needle clip, and pilot jet. how much depends on a lot of things and your going to have to do a bit of experimenting to find out what works.

do a search on here and i'm sure you'll find all the info you need.

Oh man, that sucks! I heard 440s make your engine so unreliable, however this is what I have heard. Whether this is true I don't know. Hope U find an answer.

if they are built right they can be very reliable. so much so that the time between rebuilds is more than you would normally feel comfortable.
