Replacing valve seats is easy and can be done cheaply. If I'm not mistaken
once the crack is plugged the seats have to be replaced anyway. #4 is
always cracked between the intake and exhaust, out of 50 or so heads I've
found 2 that were not cracked. Rebuild both heads. Remember "Pinto" seats
are cheap.
