Here are some pictures and my mullings over on the head design of the I5 audi motor. more or less a discussion on the head dynamics and the head gaskets interesting design or lack thereof.

first is a picture of a spare head i have, along with a new headgasket i have beside it. yea i know the head is dirty... im finishing the car before i work on the new head!!!

This is a picture of the gasket placed onto the head, in the installed position. take good note by comparing it to the prior photo, that now MOST of the coolant passages for the combustion chambers are now BLOCKED except for the rear of the head.

Now take a good look below at the example photo illustrating the faults i see with the head gasket design. first off. many of the holes are undersized compared to the castings. however this may be for flow control. HOWEVER there are many blocked passages, some may beleive this is for directional control of flow through the block. But since the cooling water is PUSHED and forced through the engine, conversely to being drawn or sucked through the engine, i beleive that it is possible to open up new holes in proper diameter to provide improved combustion chamber cooling and higher detonation resistance.

HOWEVER i caution anyone planning to do any similar modifications strongly against, as altering the flow patterns to the head will also alter the flow patterns to the block and cylinders. Until they can prove that their alterations do not cause any negative effects and actually improve upon the stock flow pattern through the head without disrupting the block's internal flow pattern i would be hesitant on using their headgasket design changes.
there is no sense in ending up with a warped head, or damaged cylinders due to the fact you are trying to IMPROVE the cooling.
