You do have a point. as my stock mufflers don't have the heat shields on them.
i never purchased the shields when removing the fabspeed muffler and installing the originals.
Just to make sure I understand you correctly, every lifter should have one go at inserting it. Otherwise re-removal damages the new seals.
Thank you

Correct. Pulling the lifter out can put small tears in the seal and the thin wall of the lifter cartridge can be easily deformed with pliers when removing. In the pic below, you can see the bigger radius on one end of the seal to ease inserting it, but not on the other end..
WOW. amazing info. thanks for sharing.
- One more question. Sometime when the car is warm, and I start it, I hear a quick rattle noise (only for a split second).
I am being told it is the chain Tensioner. which I completely doubt.

It could actually be the chain tensioners until they pump up with oil. There is not a lot of other things that could rattle or have enough clearance to rattle. I would go with the 15w-50 or 20w-50. They are not that difficult to change.

Here's a pic of the shop manual.
Hope this helps.
I am in the process of changing the tappets. I read a recommendation somewhere to let them soak in oil for a day before install.
Since my engine is out and won't be restarted before few months, is it necessary?
On the tappet i removed, i can pull apart and re-insert the inner tube (part below red arrow in above picture). It does not budge on the new one (INA). I presume this is normal and oil pressure will do the adjustment as intended?
Thanks

Not sure the soaking in oil does much of anything. Oil em up when you put em in, put a dab of assembly lube on the foot, and crank up the oil pressure with DME removes before starting up and you should be good to go.
It definitely won't hurt but the rockers and shafts don't really need anything. The tappets do their job by being filled with oil under pressure, with just enough give to maintain clearances. They're empty as supplied and will fill up as 95_993 points out, but soaking gives them a pre-fill.
It's possible that one or more will drain down while that engine sits for a few months, so even if you pre-fill the tappets you'll want to follow 95_993s advice to crank without the DME relay in place until oil pressure builds up.
