318 I D

I picked up this 318 today Just checking the #s and parts installed on it. The guy didn't know anything about it other than it ran when some one pulled it. Anyway I thought 1967 was the first year for the LA 318. This one has 66 cast on it. What gives? looking at the wrong #s?

And then the head #s best I can make out are-2858920 , any info on those ?
Has some cool Valve covers that I have not seen. ( I know not factory). I don't know if they are old school or more modern.

And then the distributor . After market also but what ? Just got this thing home haven't had time to look it over to much. Any info o any of it. Enlighten me !!
