Portflow
They give you a choice of 3 stages (if I remember correctly).
Not sure if Portflow still keeps stock anymore. If you get lucky, they have heads already completed in stock, you send them a bare core and they ship out the completed one as soon as they receive and inspect your core. Saves in turn-around time.
But, it's winter time (race car down-time) they are most likely swamped already with work to do.
Insane quality and workmanship. Not many other big-name machine-work companies that specialize with Honda engines still around today.

Re: Port and polish b series head
same size motor, more compression, better fuel, same itbs, same cams, 4 pistons base 156 stock valve head beat a +1mm portflow(drag cartel) head by 20+hp at every rpm... the excuse was that it was an older head design. maybe they have come light years since then but that head was garbage. 4 piston head motor even made more with a stock rbc manifold and 74mm tb...

4 Piston heads look great. Since you are looking for a CNC head only. and he seems to really be dependable on you actually getting your head done.
a lot of others seem to hold your head for a year or more or just never even finish it.

Been hearing a lot of good things about Mission Critical Performance and their cnc heads. Anyone have any feedback on them?
