Which injector seals do I need for denso 600cc injectors

[dsmcoder]

I just bought some used Denso 660cc injectors and I need to buy some seals for them. What would be the best kit I could get for them?

Also I am going to replace my exhaust manifold to head gasket, Exhaust manifold to turbo gasket, and o2 housing to turbo gasket. Is there a full kit for this?

I have went to home depot and bought some firewall gromets for my injectors, have used them for over a year an had no problems. As far as gaskets go, I had bought a whole kit off the auto zone website, had everything but injectors seals with it.
