gasket set differences. Options

[technicalninja]

Quick couple of questions:

What is the difference between 1.8l gasket sets and 2.0 sets?
Is it just the head gaskets and a different intake gasket?
2.0 is out of stock almost everywhere and what's available is expensive.

I'm planning on using 96mm head gaskets anyway so the gaskets which come in a 2.0 kit will not be used.

I found copper 96mm gaskets on Aircooled.net and will either use them or none at all.
I'm planning on a quench distance of .035" using hypereutectic pistons and it might be beneficial to use no gaskets at all.

What are you guys using for front and rear main seals?
Seems the good ones are discontinued and I'm not sure what the best options are now.

Do you anneal the exhaust copper seals when new or are they dead soft initially?

What are my options guys?
I'm very brand specific when I know which brand is best.
Right now, I don't have this knowledge.
The target engine is a 73 2.0l

The muffler gaskets would also be different. Also the "intake boots" that go from the plenum to the intake runner pipes, but I'm not sure those are included in a gasket set. Ditto stuff like the cold start valve gasket, and a couple of other things in the intake.

There are a few things that list different parts but that I'm pretty sure can be interchanged. I believe that the copper exhaust rings are examples of those.

Thank you Dave!
That's the information I was looking for.
