One of the best things you can do is to buy a book like this one:

or this one:

Your head is an open-chambered truck head, oval port with 2.06/ 1.72 valves.

The crank is cast. Nothing wrong with that on a street motor, though.

The block number was misread or mistyped. It is 10069286. 1990-91 4-bolt main.

You can build a really good performance motor from this one, if it is in good shape internally. However, 10.5 - 11.0 compression will put you in Ping City.

Something around 9.6:1 (iron heads) or 10:1 (aluminum heads) can be run on 93 Octane. Be careful, though. Too many folks grab a huge cam and large port heads and end up with an engine that's not worth a crap on the street.
