just wanted to know if a b16 ported and polish head done by portflow still pass smog in CALIFORNIA if installed to my b16a3??? bottom block will be stock but for the head it is done by portflow with supertech valvesprings, itr retainers, itr cams. the rest of the motor is pretty much stock just dc header and aem intake.

 

it should. have a super good cat and muffler and see what happens lets us knwo

 

anyone on here pass smog with a milled p&p head???

 

dont see why it wouldnt, theres no way they would be able to tell inless you tell them.

 

id say ya, just make sure u dont tell them like 98civdx said

 

as long as there are no cels and you have a good cat and muffler i think you should be fine

 

i need some california peeps to answer this cuz we got the dumbest smog rules here.

 

no one???

 

should actually HELP on the P&P, the milling is what I am not sure of.

 

just talked to my buddy with a pnp head oversized valves, milled and he still passes no problem. he lives in Sacramento as well.
and on the off chance they do ask, just tell them the motor was rebult and you milled it because the shop reccomended you do

 

ok thanks.

 

yes you will pass

 

doesn't milled head = higher compression = more nox? just a question...

 

well yes. but you only mill so much,
whitch isnt going to rasie comp to much.. he only did it to make sure the head was flat.
but if you are worried about it you can alway put a thicker hg in and the should lower it right back to oe.

i doubt you will even see a half a point raise in comp. although i may be wrong.

 

As long as you don't weld the combustion chambers you should be ok.

 

When they surface a head, they usually only take a little tiny bit off. Would the cams allow more unburnt fuel to pass through, since they probably have more overlap?

Let us know how it turns out.

 

i thought resurfacing was to make the surface of the head flat, and milling was to bump compression? all this is confusing lol sorry
