406 sbc, build questions

Hi, I'm a new member and have some basic questions about a 400 sbc that I'm putting togethor. The following is the information I have about the engine:

Valve Guides
Tapped/Studded Rocker studs
Combustion Chamber: I was told 64cc but the 416 head is 58cc right?

Cam Style: Hydraulic flat tappet
Basic Operating RPM Range: 3,000-6,500

So, I'm sorry to data dump but this is the engine I recently purchased as is. The application will be for a pickup I'm building (K30) and will be using it for fun mostly, definitely want to run pump fuel in it. I've had it running previously with 93 octane and it was very strong with great oil pressure.

First question: is this set up any good? or what should be changed?
Second question: I need a head gasket, what gasket should I get?
Third question: what kind of numbers can I expect from it?

Thanks guys for any input, I'm a novice, with very limited money (recently married) and just want something fun and reliable.
