Engine/heads?
#2
The 2 being the last number means it's a 1972 motor and 395558 is the casting on the Olds 350 motors from 1968 to 1972.
The heads will have a large number by the #1 plug wire. That is what heads it has

5 is supposedly the best flowing stock heads. 7s are the first year that "should" have hardened valve seats for unleaded fuel. I've got ported 7s and they do quite nicely.

What kind of parts?
Most everyone is good...except for Mondello and a couple of "Brothers". (I can't say the name of the "Brothers" company because they have taken legal action against some folks who got screwed by them and then had the audacity to complain about it on Oldsmobile boards.)
Just say away from Mondello and the "Brothers" (whose company I can't publically name).

Depending on what you are looking for, you should be fine with the 7 heads. The 7 heads are from a 71 and 7a's are from a 72. The 7a's definitely have hardened seats but I am not sure about the 7's. Both heads have small combustion chambers which is what you want. The 72 used dished pistons to lower the compression to 8.5. The use of flat top pistons will raise the compression which will be offset in part by the thicker head gaskets available today. Hope this helps.
