is there anything i should look for to make sure this is a clean engine that wont breakd down on me???

also how can i tell it is really a gsr head (other than the intake manifold)???

how can i tell its obd1??

anything other little things i should notice to make sure its gsr????

 

obviously the block b18c1 i'm trying to get more of like tips to see that it doesnt burn oil or just precautious stuff??????????

 

look at the fuel injector and you can tell if it's obd1 or obd2 obd2 have the easy take off clips. obd1 is the one u need a flat head to take off the clips. also the distributor can tell you if it's obd1 or 2. if the head says P72 it's gsr if it says pr3 its a b16 or ITR. and most important part is make sure it's legit and not stolen. (receipt or paper work and make sure the serical # or engine # that's under b18c1 is still visable and not grind off) you can also do a compression test use a compression tester and a battery by hooking it up to the starter and crank over the engine and do a compression test to make sure the engine have good compression.
GOOD LUCK
