How much boost are you planning on running?

Depends on the boost setup and the psi. Blowers like heads, turbos don't care all that much. Its always a plus though.

Your pushing air threw it but you got to make sure Ur value springs and load is righ or eles can cause value float and beat Ur value train up been their done that

Ported heads = more power with less boost

If you have the money, go for it.

P&P heads will have less restriction, which will flow more air. Which will make more power with less boost and ever more power at same boost less once you turn up the boost. If you can get PP heads do it.

If you can get a good set of heads that make 50 hp na then that'll be around a 100 hp gain around 15 psi boost. That's a nice upgrade
