On the Nar-Spec.com website they have porting. Street port for 350, and raceport for 700.

Here is a pic of some of the porting, but im not sure if it is street or race.
Edit::ic cant be linked go to the website.

I was just curious how many people have dealt with them and how well they did and what not. I see that rodrez did some of the pics, so it seems like a few people on HT have dealt with them.


TIA,
Eric

 

for the street port it says they only go 1.5 inches into the head....

Why even do a port if its only touching a little bit of it. Go for the one that does the everything.

Also, when choosing a company on porting your head. Make sure they also offer, Valve job, new valve seals, resurface the head, hot tank, and assembly.
These are needed for a proper reconditioning. You dont want to put back a half assed head on your car after its been taken apart.

 

and that company is VERY young. IMO

 

here's a post w/his work from Rocket's site:

Looks pretty clean to me.

 

The work looks decent to me. I dont see why it matter so much how young his business is, if he does a good job then he does a good job.

And it seems he does a decent job for not much cash, 1.5 inches seems like a bit to be opened up.

 

anyone can clean up the first inch of the ports. if you are going to do anything to the head, invest in something that will port all the way through into the valves. Its kinda like saying, i'm going to get a dope *** block built but i'm going to reuse the bearings in that block.

Look for work that gets deep into the head. With consistency on the ports.

 

Oh ok now I see so he only ports an inch and half into the head? Whereas something worth the money to go all through to the valves?

Also, ive read that valve jobs are best thing to do to the head. Iv read about 3 angle and 5 angle, whats the difference and how do they differ in performance/price?

Its not that Valve jobs are a good thing to do, its more of a HAVE TO.

A good port job will take the complete head apart, valves, etc. and work through the ports and up to where the valve sits. A head Should be Hot tanked to thoroughly clean and get rid of all the material that was grinded off. You dont want that falling into your block dont you?

Also a Valve job is recommended when redoing the head. When you put back the valves, dont you want the valves to sit properly on the head and have a good seal for best results.

Its one of those quotes again. " You get what you pay for"
A good job done properly will give you the best results.

 

I see. Id expect more people to chime in, headwork always seems like a grey spot here on HT.

Id like to help others out, and learn more myself.

So here is a bump.

sorry man i dont understand wut ur syaing r u tryign to say nar-spec porting job sucks cuz its rough and this guys is good cuz it smoothe.

wutever your trying to say you want something that is rough. fawk how it looks your buying it to see a difference in performance. but homeboy is right the valve job matters a lot its where you get most of you power and you want to make sure that you valve are seating correctly.

the exospeed the divider thing in the middle looks a little too thin. or not? im not a pro or know much about head porting but let me guess correct me if im wrong a head like that is made for higher hp in ther higher band and loss of low end torque because of thin the divider thingy? em i right jus wondering

let me clarify what i said earlier.....

have you see skunk2 IM ports? they kinda ruff....and AEBS IM is rufferrrrrrrr....but still making good power bang

yes smoother porting is nice...lot more air...and velocity too...but smoothness reduce af mixturing effiency....so ruff surface mix better but too ruff is bad...so ruffness have its limits...

i personally like smoother porting job because i can adjust more fuel injected to combustion champers to counter extra air....

you're shaving the divider thinner will lose low end...because volume increased from porting......samething is applying to IM and yes you were right

but that porting job from exospeed is missed porting at the second port on the picture at the edge of the port....they shaved off little bit...NO GOOD, or maybe the camera angle is off..i dont know..but if it not the camera angle you will find it's tuff to port match

 

Exospeed, you of all people should know that the most important part of porting is the v-job. so a port match and a good v-0job will make almost as much power as a fully ported bling head on mild builds.... And if you read the post , that pic was of him just getting started on a port.. not the final product....I think people are being alittle unfair here..

Amen, he seems to a decent job for the price. I think it is fair.

 

I was under the impression that you can't hot-tank aluminum heads. My machine shop wouldn't. Is there a different process that an import-friendly machine shop uses?
