Yea I believe they worked in Liviona Mich Roush has 1500 workers
I did most of my time @ the roush camp in Mooresville ,NC
@ the engine development center. I built Ricky Moroso's engines
From there too bad he couldnt get a good car.

 

then slowed up after he went to glidden, really cool down to earth guy though, we would always pit near him(moroso) Brad moore lives in mooresville and dan worked in mich.

 

u guys think it's worth it to get killer headwork done on a LS engine?

 

Only if you get the whole package-i.e. cams,valvetrain,header,exhaust,intake, and fuel management.

 

We are doing inexpensive head work in the $600 range for B series engines. It includes disassembly, pressure testing, needed port and bowl porting and deshrouding, 3 angle valve job, spring testing, surfacing, before and after flow tests and reassembly. They won't be as pretty as the all out cylinder head pros, but they work and are affordable. We will use your parts, if desired, we don't have to sell you parts. All work is done on state of the art equipment. BTW, we can do 5 angle valve jobs, if desired

honest and straight to the point!
where is this place of yours?

 

We work out of Strader Performance in Lake Elsinore but you could also come by our home in Irvine

 

If you're in the NorCal area I highly recommend getting your head work done at Custom Built Imports in Stockton. I'm partly biased because it's my friend Chuck's shop but hey.. Chuckles (the owner) and Cloyse Holland (Holland Racing/STR) have used the heads to their fullest advantage. The heads flow more than the industry standard. All headwork is done according to engine specifications, unlike the "on the shelf" port jobs.

Custom Built Imports' number is (209) 933-9371. Call and ask for Chuck!

 

we port heads for 350 with port match of I/M, plus shipping costs

 

 

how much porting do you do for $350? do you include valve job and assembly?

 

How about flow data?

im guessing this is for me? 350 is complete head porting with port match of i/m if needed. and assembly. multi angle valve job is 250. can go a bit lower if no port match of i/m is needed

 

portflow here...

 

Go to KGRacing.net and check out there head porting jobs.

I had my head ported there and no complaints. fast turnaround too.

 

Funny, I had Kurt do a 3 angle valve job. I thought the head was great. Turned out when it was rebuild time, it was a single angle valve job. Got ripped and didn't know it for 2 years.

 

Many many people have fallen prey to the old "3 angle valve job scam".
Most machinists with old fashioned or outdated equipmenet still have to actually grind the seats by hand. This requires a lot of time and patience and the quality is very very difficult to acheive because it is determined by the skill of the operator.

The process uses a drill motor which drives a stone which is centered over the seat on a pilot. the stone is preground to a certain angle and the longer the opoerator grinds the wider the seat will get, which also sinks the seat lower and lower into the head. This causes two problems....one is that the valve stem installed height get taller and takes up the adjustment room at the rocker arm causing poor rocker arm geometry. The second is that the compression ratio is compromised by adding volume in the port.

With a 3 angle or any multiangle valve job, the idea is to have a seat cut to the proper width for the application which seal on the face of the valve at just the right spot, depending on application, and the have a top angle and a bottom angle that serve to make the airflow smooth out as it transitions from the port across the seat and into the chamber.

A fine valve job can be accomplished using this method, but it requires that the operator have three sepearte stones of varied angles, and he must be very careful to ensure that each seat is ground to the same depth and width, and because this is all done by hand, it takes a looooong time to do properly.

With modern technology, the valve seats are actually cut or "machined" into the head using a carbide cutter that has all the desired angles and widths shaped into it. This way the operator can cut one seat, set his depth indicator and the proceed to cut all the remaining seat exactly the same in about 1/10th the time it used to take and even at that the precision achieved will still be greater than that of the old method. There are different cutter shapes and sizes for every conceivable seat angle and a skilled operator can offer any level of sophistication you desire in a very short period of time!

The moral of the story is........
Make sure to ask your machinist to explain the seat cutting procedure he intends to use and be sure thay have the correct equipment to do it right!

let's see $350 / $80 an hour labor rate is 4.3 hours, .. .. hummmm, .. how much porting can you do in 4.3 hours??? I'm assuming this is a very, very basic port job with no flow testing?

wow who charges 80$ a hour???? on average we put 10-12 hours in each head we do. and we do not have a flow bench just yet still working on that

 

Timmay,
no offense, but I'll bet if you sit down and pencil it out, you will find that it's not possible to operate a professional business out of a shop with an 8-10 dollar per hour labor rate. It hard to make the payments on all the sophisticated equipment it takes to do the job properly, like a seat and guide machine, valve grinder, pressure tester, surfacer,vacuum tester and flowbench.........just to name a few!
Good luck though. to each his own.

oh i know this thats why we dont own our our own shop. we rent space. and 350 on the headwork is just a special we are offering. we usually dont do alot of hourly work mainly internet. thanks for the opinion though

 

good enough for me

 

dayam efiguy! best damn explaination, *applaud*
