any opinions on the cam wear and the cylinder walls? should i swap that cam out when i freshen the engine or are they suppost to look like that? should i have the head rebuilt? if so what specs? should i have it shaved? how much, how about valve job? 3 angle fine?!

i'll switch to 30 weight oil this weekend. there is allot of oil on my tail gate but not 4 quarts which is ended up having to add. so is it all suppost to come out the crankcase breather tube like that?

i'm basically looking for reliability 1st off and a little extra performance 2nd if at all possible
