Do you make it big so you can get volume or do you make it small for air speed? Any head shop can give
you a big hole but what are they doing with it? If your head shop did not talk to you about
every part of what you are building than you are at the wrong shop. Why don't you just flip a coin
and head in the wrong direction with the wrong parts for your application.
Your heads must be built for every part of your particular use.
Did the other head shops talk to you about:
What are you going to use it for?
What are the other parts within the motor? Cam, Rockers,What
compression our you looking for?
Tranny gears ratios?
Slicks / padals or tire size?
Weight of the car and passengers?
How fast you want to go?
Is this motor for a class?
The RPM you fell safe shifting at?
Most important the type of induction?
If not let me ask you these questions and build the best set of heads for what you will use them for.

"The biggest, badest,
VW Cylinder Heads ever designed
and put into production"

That is straight from the horses mouth
and they could not say it if it was not true.
CB Performance® and Bugpack® have done
their homework and come out
with a true winners..

Comp Elims and S/F as they are often called are one of my favorite performance castings.
This is an Excellent set of heads for all out drag racing and off road applications.
If you are looking to make some real horse power, then a set of these will get you there fast.

Aspirated ports (190 hp to 260 hp) (Turbo ports from 350hp to over 800hp)
A quick look at how I make this type of intake port work.
First: A motor is just a big vacuum pump that wants to suck away!
"Yes its a pulse pattern sucking thing!!! "(no jokes please)
So you will have to keep this pump sucking thing in mind when thinking about the intake port.
(these heads are used mostly on Large displacement / high compression motors).

This type of intake port must be very efficient and has to have the least amount of restrictions but not at the expense of losing air speed. I take each intake port and make it lead across the valve
into the middle / top of the chamber. With the assets of the cams overlap you can take control of the burn and placement of the charge. This means once the fuel and air is within the chamber you have control. You determine the size, shape and placement. So now you are controlling the air being sucked into the port and were it will burn. Add the free lift from the cam and rockers and you are making some power. This is why it is so important to match your heads with the cam.
In a nut shell; Your motor will make real torque and massive horse power.

Recommended use:
High compression, Turbo,
NOS, Supercharging.etc
