Good Setup?

I’ve got a '90 stock B18.
I am looking to build it up and was wondering what kind of horsepower you guys think I could get with the following:
1.Port and Polish heads
2.3 angle valve job
3.Crower valve springs and retainers
4.Crower cam .424/.413. int/exh
5.Arias 11:1 compression pistons
6.Forged rods
7.intake
8.header and exhaust

Need opinion on:
1.O-ring and/or deck the block
2.NOS
3.Copper head gasket
4.Any other options you all can give me
I could use help with anything (protection wise) I may have missed.

Thanks in advance
