Hello again everyone, Just wanted to let everyone know that we have begun to offer additional in house services to our ever growing list and cylinder head porting has now been added to the list.

Here is a couple photos of an ecotec head we have in the shop currently. Hand port work performed in house by Fred Jr.




Exhaust side





Intake side

AFTER a first pass to intake runner divde





Also, aside from just porting we also offer full services to cylinder heads I.E. plaining, valve jobs, cleaning, pressure checked etc.

ported heads start at $400, and a fully serviced heads ported, valve job, plained, cleaned and pressure checked start at $900.

Also, cylinder head assembly is also available. Valve spring and valve installation etc.

$400 for the head straight up, or $400 for just the service

 

It is $400 for the service. If a core is needed an additional core charge will apply and refunded once a good core is returned. We have started to offer the service alone for the option of customers sending their own heads in for the service rather than dealing with the core charge and swap etc. etc.

 

k, just clearing that up

 

This is the only shop that touches my car and I havnt had any problems and nothing but great service in my 3 years of dealing with SMG.

 

is this for the lnf too. caN you pm me a full head job plus 78 lb valve job would run me???

 

Yes this inlcuded the entire ecotec family of heads (including the LNF) along with many other cylinder heads as well.

PM Sent.

 

any flow bench numbers? and yeah PM me too about 78lbers and a full port and polish ..

or for full head assmbly

 

will definitely have up some flow bench numbers. the head pictured will be hitting the bench within the next day or two

PM's sent

 

Great price. Is this for a bare head or does it include for heads that will have to be disassembled?

 

good stuff, so if i got a head done from you guys could you put it on as well, its beyond my ability to do myself

 

the $400 option is porting only on a bare head, however most of our customers that have purchased these services have opt'd for the complete head service which includes dissambly etc. or have opted to upgrade valve springs which would include a service fee for installing new springs.

BUT, we want to offer a variety of levels of head work pricing to cater to everyone.

keep an eye on our website as it is under construction. we will have cylinder head porting under a list of services etc. with a full price break down of option etc. For further information PM or call us and we can give a direct quote

We definitely can do the install as well. Many of you may not know we also offer full service engine building as well.... you will see a post shortly of an engine build we are doing know for an 06 SS/SC which consists of a Bates 2.2 Ecotec race block

 

very nice.

 

sub'd for numbers

 

the level of work SMG does is of another level not equaled in the area, they work on V8s, as well as 4cyls, and if you saw the builds i have in person its amazing the variety, yet the one thing that remains equal is the quality and attention to detail.

 

I wanna see the flow numbers.

 

i would like to see flow numbers as well, it doesent look very aggressive to me and alot of material in the bowl area is still present. this seems more like a clean up job if comparing it to a m2 race cnc port look how much was removed around the guide's in the pocket, i hear this is were flow comes from.





not trying to knock your product/services just looking for more information.

 

Definitely will be having flow numbers posted up soon...will be getting bench tests on multiple heads tomorrow (ecotec and non ecotec heads.)

We will have to post some additional photos of the head in it totally complete form. On the intake side we went through and knocked away alot of the guide that sticks down as well as cleaned some of the material around the guide also. If you look, we pay alot more attention to the exhaust side of the head, the more common problem area for these heads. More aggressive port work would help on the intake side of the head if it was an N/A application or a much higher power app. i.e. 650-700+ hp, however the gains on intake side become less relivant with forced induction, which is where most of us are. Exhaust side however yields the most performance gains with the ecotec head.

 

flow numbers?

 

Just got finished bench testing the head....and the results have been very nice! about 10% gain over all on intake side and about 15 on the exhaust side significant flow increase over a factory head... exact numbers are as follows:

these are the numbers from the test from .300 lift to .500 lift (through an ehxaust tube)

STOCK intake side: .300-218, .350-233.2, .400-244, .450-248, .500-254
Ported intake side: .300-220.6, .350-246.4, .400-261.56, .450-270.07, .500-278.63

STOCK exhaust side: .300- 155, .350-158.7, .400-164, .450-166.51, .500-170.58
Ported Exhaust side: .300-170.5, .350-177.53, .400- 185.81, .450-189.21, .500-196.06

I will be starting on another ecotec head next week to try a few additional tricks to see if and how much more flow we can pull out of these heads

 

those are pretty good numbers. You can get a tad more flow on the intake side for sure, even for a mild port. Exhaust side is very impressive, especially at the .500 mark.

I haven't seen the pics you've posted, but how much did you actually open the ports up? Did you open the ports up a lot? Or mildly?

On my head, the intake ports are still stock, it was just the bowl work around the valves that got worked, and my intake side outflows yours slightly. On the exhaust side, the bowls were worked again, and the ports were opened up slightly.

 

Ports on intake side stayed basically stock size. Cleaner up the entire runner and did most of the work on the intake side in the turns into the valves. The exhaust side is where we spent our most time opening and matching the ports to the exhaust and the turns from the valves out. We are pleased with the results, and will be changing some of the things we do on the intake side for the head that it currently getting ready to be ported as we speak so we are confident to get additional gains from the intake side in the future.

Thanks for the comments we looking forward to trying more and more on the porting side of things to continue to try and extract as much as we can for flow

 

well, you are definitely on the right track. That head you just finished is a great street ported head, and would definitely help someone make some nasty power.

 

Nice Fred! Soon enough we can see whata this will do when thrown on a 35r car.

 

nice work... i might interested in some work from you guys...what might the turn around time be if i sent one to you
