Total Seal Rings have a great reputation and they deserve it. The one problem they seem to have, though, is that the rings have a really hard time seating in relatively small cylinder bores like those in the 81mm 4A-GE. Other Toyota motors with more displacement and bigger bores have no problems whatsoever.
My advice? Unless you're running insane amounts of forced induction (15+ psi) and/or high cylinder pressures, I'd highly recommend sticking to the OEM rings. It's my personal opinion that having to worry about the rings seating right away isn't worth the small gains which, in this case, is less combustion pressure leakage and blowby. Again, this applies to the 4A-GE only.
Also, note that there are instances where the Total Seal rings have seated properly, but even those engine builders admit that they take forever to do so.
You've been warned, so it's ultimately up to you to decide. I just wanted to give you the entire story on running Total Seal rings in the 4A-GE.
NOTE: Make sure that you choose the correct ring for your 4A-GE! Earlier 4A-GEs have a 1.5 mm #1 compression ring vs. the newer 1.2 mm #1 compression rings!
