If you plan on going for more power then you'll benefit from the GT spec headers, but you'll need a Harvey up pipe to avoid lag. Ported are fine at your level but may prove to be restrictive if you approach mid 400s.

I'm currently at 440 on Harvey ported headers and up-Pipe I have a set of GTs and a Harvey up-pipe ready to be wrapped and fitted, I expect to see a good improvement.
