Default Tornado Engine Rebuild Questions

I am in the process of reassembling my Tornado engine after rebuilding the head and putting a new piston in cylinder #6. I have a couple of questions.

How tight should the timing chain be? My seems loose but it looks to be in good shape. I did not see anything in the manual about checking the timing chain to see if it needs replacement.

Second, I know this has been discussed somewhere but maybe someone could refresh my memory. The rebuild gasket set that I purchased from Memphis has a rear main seal that is significantly different than the one that was in there. It is smaller but seems to fit in the slot ok and is the right diameter, but it is not u-shaped like the one that came out. Will it work ok? As the other type of seal still available? If so where can I get one. It looks like it would seal much better but the one that was in there is definitely worn and brittle.

Thanks in advance for any help. I will try and post some pics later tonight.
