Im talking about the valves and spring. I could of got those parts for 600 total. I did my own porting on my head. I have been doing porting for friends for years, turbos blowers heads ext. I think I know what im doing and talking about. What you had done you should of been charged about 1,700 tops from a vendor. It's not, you get what you pay for. It's just how stupid you are to pay for something.

you tell me what your valves are made of. If there stock size or over size. How many finger keepers on them 2 or 3. tell me the info. I'll get you a price. "So now it went from you paying 3000$ to it was a present, and you know the owner"

Note Ferrea make all there valves out of a special Alloy to begin with. and i can get your "specail valves" for $336.57 any size from stock to a few +mm

Im not trying to be an ass man. I'm just saying if you or any one paied that price, "you'd be a damn fool"

 

When I got mine done, although I never dynoed it afterwards, I felt I lost hp. U can ask Bika as well, my car felt like a dog after it got done.

Thats y I traded it in on a new 09 SS....suckers didnt even know about that poor car

 

did you have supporting mods. and tuned?

 

single groove, stock size, and im waiting on a phone call from dave for material and these valves were bought from ferrea not a vendor. and springs are dual springs. and dont be upset that i got a present, put it this way if you were to go this route it would cost you $3000 and i cant seam to find where i said that i physically paid out of my pocket, only saying what it cost. and i dont see why its even matters.

and TTR has the regular ferrea valves on there for $400, not custom

exhst is pyromet (use on top fuel and in the G.M. racing program)and intake is super alloy Ferrea does not sell these valves, they have to be made. and they are the same exact valves size and all used by G.M. in their race cars

 

your problem then is that you went custom for no reason. bigger valves don't even flow much better. my machinist told me on this head, oversized valves do little to nothing. euthenasia <sp> here said the same thing, and when i posted my flow #'s it was verified.

as for getting what you pay for, this guy is top notch, supposed to be the #1 guy on the east coast for tractor pulling heads (high dollar heads that costs more than a brand new cobalt lol) so i took it to him, he said he could turn lsj heads out for about $500 all day long and get numbers like these or better (if he could get a junk head to cut up and see what the internals look like)

 

I had 3" intake, ported tb/sc, ported intake manifold, head ported, meth injection, zzp h/dp combo, 2.5" custom exhaust...thats what I can remember

i didnt get bigger ones they are stock size

 

Horrible question with no real answer. There are so many variables to this questions it's retarded. I don't see how you could even ask this question and expect a real answer.

 

i love it when people spend money in all the wrong places, or change things for no reason what so ever in their "quest" for power.

i have less than a grand in my ported head that has been collecting dust in my garage for over a year that will hammer the ass of 99% of the "ported" heads on this forum.

BTW, for power numbers

 

what a bitch fest......

 

clearly your priorities are wrong, cause without those $1000 valves, you can't be sitting in a parking lot with your buddies and strike up a conversation of how you just got $1000 custom valves in your 300 hp car

 

ill let you know in 2 weeks. but yeah i didnt spend close to what u spend on port work

 

i can tell you this when u snap your valve and waste a sleve, damage your head, and piston you will be spending a lot more than i have

its really not that hard of a question, i asked for the increase in power others have seen with their ported heads. i did not ask what power i will be putting down.

 

clearly i fail at making power with the s/c lsj.

fml.

 

this started as a easy question asking what power others put down with a ported head. now i am being bashed for receiving a ported head with expensive valves and springs for Christmas. and area47 nobody said you fail at making power, i didnt and reading the rest of the posts i cant see where anyone did, you may not fail at power but reading... has yet to be determined.

 

anyone with a half brain in engine building knows the key to unlocking the power is in the head. Ya'll quit kidding yourselves if you think different.

Selfinfliction, that's a decent head. Similar to my head when it was just mildly ported. 350 port job to be exact. Granted, I had another 350 in the valve job and then 360 in the valve springs. But that's a decent head.

That's still not what this head is completely capable of though. That's looks about like your average decent port job. You can actually get much larger numbers out of it, but you'll have to pay someone a lot of money to do it. Like you mentioned already, cutting open a stock head to see how far you can go and to see the areas of improvement is about the best thing you can do. But that cost money.

 

i think the problem is that noone does a real test bed engine dyno run ported versus unported so its not possible to really know and folkshere dont have an answer , just a guess. GM did not guess, and if you read the build book its clear.

I beleive that anything less than an exhaust flow number of 200 at 400 lift is not in the game, and hogging out the inlet will make the head produce less power no matter what is done to the exhaust....

 

word

 

absolutely.. and once i'm ready, i'll be sending you some funds to fail tweak my tune

yeah, euthenasia showed his head flowed much better. the guy said he knows he wcould get more out of it, but he has never done a 4 banger head and didn't want to get crazy on it unless he had a junk head to cut apart and see the inside

 

whp you could gain. 1-40WHP

 

SMG is the only vendor on here that will do an aggresive port on a head. im saving my pennies now for mine along with valve springs

 

hope SMG has better #'s than what's posted, cause my head flows 10cfm more on intake and their exhaust flows only 3cfm better

i would hope for much higher numbers on an "aggressive" job

 

slow the cocky train down and re read my post VENDOR, are you a vendor? ok now that im right you can continue

 

i'm not a vendor, and i don't do port work.

it's all gravy though if you want to waste an extra $500, hell while you're at it order a set of $1000 custom valves too


apology accepted

 

waste an extra 500? and where else would i get quality work like Fred at SMGs done for a cheaper price including shipping/ if anythings wrong i can drive there in an hour and have stuff fixed usually at no additional cost? correct again i know
