Installing Camshafts/Valve Springs

[red_sir]

I'm planning to install camshafts and valvesprings in my S13 blacktop motor. I was wondering if these are the correct part numbers for the gaskets I will need.

Rocker cover gasket 13270-53J05 (x1)
Plug well gasket 13271-53J02 (x4?)
Center bolt gasket 13270-53J13 (x1)
Chain Tensioner Gasket 13079-2J200 (x1)
Chain Tensioner O-ring 13069-53J00 (x1)

Do the spark plug well gaskets come individually, meaning I will have to order 4 of them?

And also, do I have to worry about valve shim clearances when only installing cams and valve springs? Will it be alright as long as I do not mix up the shims?

Thanks.
