Honda accord smoking problem

I just got this 82 accord I found it in the back of some old guys property. I got it running pretty fast and it runs amazing good power idles good but it smokes a good amount but not all the time. It will clear up than come back. The plugs are not getting fouled and i used some sea foam and it got better but it came back. Im not sure what it is. Anyone have any idea?

And the car is for sale if anyone is looking for one http://img.tapatalk.com/d/14/04/16/uqe4abag.jpg

Most likely it's the valve guide seals.

Okay cool ordered them today and will be replacing them thank you!
