Benifits of Porting and Polishing Head?
waht a port and polish does is you are makin the ports bigger so more air flow comes in and that equals more hp. yes its beneficial for FI. i got my head PnP, 4 angle vavle job, and manley vavle springs. good luck with it.

So the new head and the crower internals offered by TrueHonda are a good idea for FI, Im assuming. How much PSI do you think I can push with all this done?
With all the crower products and some lower compression pistons probably about 15 psi i wanna buy all the crower products and low compression pistons and some other **** and run 15 psi but i got a D17A1 not an A2

I drive about 40miles a day so I was just planning to run about 10-15psi on a daily bases and be able to push a little more when needed. So I guess the stage 2 products it is!
Thanks for the help guys.

Anybody know how much more boost you could run after a pnp? Dont they usually run a couple hundred? Plus a new HG.
