Clevite 20018R O ring, nylon ring and thermo gasket question

[Carlo]

Starting to assemble the bottom half of my stroker. I was checking the gasket kit and couldn't remember these 2 items were for:

1.what were these o-rings for. There were 2 bags in the kit.
2. Nylon ring.
3. 2 kinds of thermostat gasket, am I supposed to install both or just choose one?

The nylon ring is for the oil pan drain, use the grey t-stat gasket unless you like cork. The o-rings should be for the fuel injectors if the total is 12.

Yeah the o-rings for the injectors come in bags of 6 ... or at least thats what the mopar ones i ordered did. There should be two bags.

Not sure why it came with two thermostat housing gaskets thought. Pick one??

Use the one that fits the best. Looks like a slight difference in the slotted part.
