cam bearings

hey guys,

i was wondering how hard it is to remove and install cam bearings on my engine (440)

is this something extremely hard to do? or can i do it myself? i know i need a tool but im pretty sure that i can rent one from a tool place by me.

any help would be great, and if you know any good article or videos it would be a huge help.

i would like to learn how to do it.

and finally is the install tool the same as the removal tool?

thanks

marc
