ok i have a stock b16a head i am puttin on my forged ls/vtec i have all new oem valvues in it com cam springs and i am still llookin for retainers but i am running gsr cams!

wile it is at the shop gettin all decked and **** is it worth a P&P? or i here they flow ok stock!

 

If you've got the money to throw around go for it.

 

is it worth it?

 

of course it is..

 

money would likely be better spent elsewhere.

i guess it depends how much you pay for the p&p

how much power are you trying to make?

 

in the 400's

 

what have you already got and what do you plan on getting for your setup?

 

u dont need to port the head for 400hp

 

I was wondering if it's possible to reach 450-550whp with a stock b series head (whichever head it maybe) is it necessary to add aftermarket parts to the head to reach those numbers?

 

on vtec heads, no

Non vtec, not really, but it will help alot more than if it were Vtec.

 

i have a stock block ls with egale rods wisco pistion 8-1 stock crank and a b16 head with comc cam spring oem replacement valuves gsr cams abes intake manny devided top mount wit a hx35 and some percision 1000cc injectors gsr tranny! lookin for the 400 rang

i would definately throw aftermarket springs/retainers in the oem head.

 

i already have comp cam dule spring and i still need to buy retainers!

 

i wouldnt bother porting until 500+ even then its not necessary. money would be better spent on other parts that make more power or provide a better powerband, IE itr cams, gt series turbo, sleeved block

 

i am shootin for a sleeved block for next season!

 

awesome sounds great, just get a good valve job for the new valves, which im assuming the shop should take care of.

save the dough for the sleeved block next season

 

woo i just seen down there you do tuning in NY! i am going ot need my set up tuned in about 4 to 8 weeks from now.

insterested?

 

pm sent.

 

I'd say portwork is a way higher priority than sleeves for 400hp. Actually, portwork is a high priority no matter what. Would you rather get the portwork and run lower boost (i.e. have a longer lasting, more efficient motor) or skip the portwork and rape your less efficient motor with higher boost?

I personally spent a grand on quality portwork and skipped the sleeves. I don't regret it one bit. The difference before/after the portwork was night and day. If I had spent that money on sleeves, I wouldn't even be any faster - I'd just have bought a larger safety margin for my tuner.

well that's the point of sleeving the block as far as I'm concerned, but I've just noticed more and more people putting down big numbers on stock cams and not really touching the head. there is no question that you can benefit from it ported head, cams and springs. I'm wondering if it's totally necessary to upgrade parts to hit those numbers? or could a totally stock head suffice? this is of course also assuming your using the stock redline

 

People are too obsessed with "making numbers." I'd rather have a well built, highly efficient motor than a stocker with nothing but a huge GT turbo.

 

gt series turbos are just about making numbers? they can meet any powergoal and supply the best powerband.

gt series turbos are "huge"? they have an endless array of turbo sizes to support any powergoal.

i think the stock head is efficient enough and better gains would be made with a larger bore on a sleeved motor.

if i had to do it again i would have gone stock port on my build. but when it came to sleeving the block i have never looked back.

 

this is at your discretion really, obviously youre getting mixed opinions. when you port and polish your head, it will flow so much better that you can make the power youre aiming for at lower boost, ie safer for your block- especially since stock sleeves. id call around and ask for some quotes, i dont think you really need to hit up headgames or portflow or rlz although they are pretty much the best in the business.
i have a 60-1 and im wanting to make 350whp on like 8-10lbs so i did the p&p on my head and am gonna use itr cams to reach my goal. it all depends on your budget

You missed my point on all counts. I was making reference to idiotic h-t trends that I refuse to buy into.
