question about rockers and compression

Sorry if this is something super basic or normal, but I sold my old 62 a little bit ago and bought a 1969 short bed. The p.o said the motor was rebuilt 31k ago but when I bought it, it wasn't running. I got it going after I got it home and trying to time this thing was a nightmare. I'm not sure if the cam is degree'd right or what, but I also had some massive valve cover leaks. When I popped the covers, I noticed the intake manifold sat really high and was hitting the valve covers even after they were notched. Is that normal for a RPM Air Gap manifold?


Secondly, some of the rockers seemed a little funky. I've never messed with roller rockers so I don't know what's normal but when they are loose, the only way the roller and valve line up is at an angle, but then I noticed the pushrods were coming into contact with the hole in the head. There seemed to be a lot of debris and grainy stuff in the oil as well. Not sure what is going on there.

Lastly, the motor was running all weird, so I took a heat gun and pointed it at all the headers and noticed 2 and 4 were still cold. I checked to see if they had spark and they did. I thought to do a compression test but what I got was :

1: 180
2: 180
3: 180
4: 180
5: 155
6: 180
7:165
8: 180

I'm just lost now and maybe if anyone knows or has any input on any of the three issues I have, it would mean the world to me. Thanks again everyone!
