It is not normal, are there new or old tensioners in?
can you post up a pic of the front of the motor with the cover off? They should be tight, one should not be significantly looser than the other. Does it look like the tensioners are in the same position from side to side? And when you say the drivers side one is compressed, what is exactly do you mean? It is compressed and is not putting tension on the chain, or the chain is putting so much pressure on the tensioner it is compresing it?
Also, let me throw this question out there because I have never rebuilt a modular motor. Is there a right and left timing chain? Are both sides the same length, or are they different from side to side? Just for shits and giggle I would try swapping sides and see if the tension is still out of whack.

The chains are identical. The only thing I can think of is that the tensioner on one side is collapsed. Or, you are putting old stretched chains back in service; are they new? How many miles?
Not that I have any experience with OHC engines but I would assume it would be pretty tight in order to keep valve timing accurate. The other side should definitely not be loose. Pull both chains and see if they are imdeed the same length or count the links. Then reinstall them on opposite sides. If it is still off there has to be something wrong with the motor. Something is not adding up correctly.

The tensioners due use oil pressure, but a new tensioner has enough pressure to apply moderate pressure on the guides.
When I did cams, chains, tensioners and guides about 9 months ago, I replaced everything new. Everything was nice and tight but not as tight as it seems the OP is describing it. It sounds like something is not right to me. Are you sure you got the correct chains?
Also, can you post up some video or photos?

They do require oil pressure to pump up. Maybe that side needs oil pressure to tighten things up. When I assembled my motor I adapted a garden pump sprayer to the AN fitting at my oil filter manifold where my oil pressure gauge line connects. I added a few qts of oil to the sprayer and watched the tensioners pump up along with the rest of the motor which was completely pre-oiled.
Also, there are tiny little micro gaskets behind the tensioners that act as o-ring seals. If the tensioners were removed they must be handled with extreme care as they are very delicate.

I replace timing chains, guides, and tensioners on my old 2v gt which is a similar scenario I think, then I swaped the chain and guide set over to another engine when I switched out engines. so I've don't this twice, one side was a little tighter than the other chain. you just need to make sure you compressed both tensioners all the way, if one is out farther than the other it will do this. it was also a bitch to get the chain on one side and easy on the other. as long as all of your timing marks line up you should be ok.
I used the otc cam holding tools when I did mine. not sure if these are supposed to be used on the 3v's though.
what exact parts did you replace that your having to deal with this issue anyway?

Sounds like it needs oil pressure to pump up the tensioner

as long as you can turn it over and the chain isnt gonna skipp any teeth on the cam or crank gears it should be fine, i wouldnt woorry about it. it will tighten up with oil pressure once it gets to the tensioners

yeah, that doesn't looked pumped at all. Starting the vehicle will probably do it.
