I bought a felpro lower gasket set, and I've basically got the bottom end and head done, I have a lot of o rings and washers left over from the kit, just curious if you guys know where any of them go.
Thanks

One of the small ones in the bag is probably the dipstick tube o ring?

The 6 bolt used crush washers for the oil squirters, but the 7 bolts definitely don't. That's a lot of washers.
 
Many aftermarket gasket kits always include something you don't use, like oil pan gasket etc.
As for the o-rings, on a short block mainly you should replace oil pump castle plug/dipstick tube/water pump pipe o-rings.
As for the crush washers, even if the block is 7 bolt, if your block is from a turbo 1G 7 bolt or a JDM turbo 7 bolt such as early EVO's, RVR's etc, you would need those washers.

I didn't end up opening the oil pump, it was fairly new and seemed fine
If the oil pump is still apart from the block, I suggest to inspect the oil pump. It's not difficult and it doesn't take long. The oil pump is one of the most important part for the engine. You shouldn't put a guesswork on it.

The only seal for oil pump is the one that goes on the front case (it’s not an oring) and there are no seals internally. The oil pick up tube is a flat gasket. Same shape as the one for the turbo drain. Like Hiroshi said, it’s probably extras they throw in there.

Thats too broad of a statement. 1g 7bolt used bolt in squirter. 2g 7bolt do not. Side note this is also one of the theories behind 2g crabkwalk because the squirter are fed from the main oil galley on a 2g.

There aren’t that many orings on a 4g63. I can only think of 4, cas, dipstick tube, biss and water pipe.
Not specifically to shortblock but there are others. Power steering. Injectors. Oil pump castle nut.

The felpro kit shouldve come with a parts breakdown.

Cas? Cam angle sensor? I just finished installing that but didn't see a place for one, it's a 97-99 style sensor

Yes. 1g does have an oring on the cas. Not sure for 2g

Correct. I was just talking about long block in general. Still not that many

The 2Gb CAS has an O-ring for the sensor to seal it with the housing. The housing uses a "gasket" (RTV) to seal against the head.
