[QUOTE="jonboylaw, post: 552339, member: 17621"] Getting hold of good quality blanks is difficult and not everyone wants new heads, but it is an option. Another point is that the stock valve size is sufficient for a bus application, making them larger means widening the ports and this drops the airflow at low RPM which is not what you want for good torque. Those heads would be better suited to a beetle in my opinion. I run stock valve size on my twin drla 1955 motor and that pulls very nicely indeed.
