head and short block combonation

[Roc_pitbull]

I'm looking for some advice on a head/block combonation.

I want the bottom half to be 2.0 or under. and I would like to have the best flowing head that will fit on that block.

not sure if this is important or not but i have absolutly no plans on using forced induction. I do want to be able to run it often on high revs (racing).

thanks

block:
- b18a/b/c
- b20

head:
- b18c
- b16

Thank you, So it'd be best if I were to get the b18c long block.
