Give the OP a break. Lets see any of you post semi fluently in Hungarian!

Hes not doing too badly, but his English will improve with practice.... as well as his porting. I wasnt too impressed with what he was showing in the videos.

Hi!

Yes, we really do accurate work as an Italian tuning yard. But this is
our Hungarian product.
All components were made by non-series hand-made technique
which procedure increases efficiency and life-time of the pieces.
The motto is the following: Long lifetime and fairplay is possible as
the result of the highest efficiency with great accuracy.
You are right. As I've mentioned this kind of treatment makes surface
much stouter. Our hand-made rolls promise 3 or 5 times longer life
compared to piecies which were made by mass technique.
Taiwanian rolls has required thickness and proper cooling. Our engine
is equipped with larger shovels in the cause of better cooling.
Testing is going to start soon. Results of measuring will be made
known as soon as possible.
Until that time several video is avaible on Youtube. I'll send you the links.

Greetings:

That hole tapped into the middle of the intake port is designed to catch oil for the left main crank bearing. What happens when it is no longer the low-spot in the tract?

[Trafficjamz]

What is the point in going that large on the intake? Won't the flow of air bet met with the side of the crank now?

In my years of fooling with porting blocks all i can say sometimes bigger isnt better..
There are few different ways to port a block, it depends on what your trying to achieve....
