a quick breakdown of valve shrouding:
the cylinder is not wide enough to allow the effective use of large valve heads. The valve will be very close to the cylinder wall and cause an obstruction in airflow, hurting performance.
If you cant get a lot of air and fuel in, you wont get a lot of power out of it.
