Given the mods I have done to the car, see sig below. Is getting a port and polish worth it? I dont have cams or aftermarket valve springs and lifters. But Im getting the motor rebuilt soon and considered this since the motor will be torn apart.

Dont plan to replace the cam and get more aggressive springs and lifters. So will a P&P be worth it?

 

just intakes or heads too? i would say yea go ahead since its gonna be apart. especially if its both intakes and heads.

 

yea do both heads and intakes. and a nice cam would sure help it out

 

What kind of power gains are you looking at if you get just PP upper and lower?

 

Dont forget the MAF, if thats not opened up you P&P wont be able to perform as much as it could.

someone answer NAOWAH. im waiting on my ported upper to come and im planning on getting the lower and throttle body done. power gains??

 

procharged your looking at 20-25hp gain.

NA 5-10hp gain

 

the maf does not need to be touched nor should it be.
agreed, at least on NA, dont know much about gains on f/i

 

Is the supersix power pack, the one with the P&P upper lower, cylinder heads, and cam shaft, really give you an extra 70-90 depending on which one you purchase?

 

port and polish! The best way is to start your car, then connect a tube from your intake and just place the tube in a tray of sand and the sand gets sucked in and polishes the intakes right where it is needed!
