I was starting to wonder if you were getting anywhere. I guess the best way too describe "coil bind" is turn the crank pulley(with valve covers off), and watch the problem valve until it is completly bottomed out. Then if you can't see a gap between each coil of the spring... you have coil bind. I'm sorry i'm not very good at internet directions, more of a "hands on" kinda person.
If the case deck, or heads have been machined different from bore to bore, then you couldn't seal the cylinder too the head correctly, leading to major leaks
, or cracked head or case
.
As for your cam. When looking at the cam out of the case (i can't remember if you can see this with cam in case, while heads and pistons are off) , you should check to see if the cam gear was installed correct. There is a mark on the cam gear. The lobe on the cam farthest from the gear should be facing DOWN. If not, your cam timming is way off (carbon and oil on pistons, poor running, or not running) then this would be your problem (I forgot about this in previous posts
)
