Mod Quad head is better for 3 reasons. Better cooling then the other 4 listed IN THIS video &, Its a one piece design (less o-rings) & it uses stock studs so u don't have to change the studs out like the pro design because Some times taken studs out can brake off in ur cylinders.

This was a good video with a nice comparison but Its hard to hear you at some points.. If you could speak a little louder or maybe get a good mic this could be a really good series..
I too had difficulty understanding in several passages; Being European and not an English native speaker, I thought it was my problem. Reading your comment I realize that it's not just my problem; Now I feel myself a little less stupid
I would have preferred some practical cooling tests with temperature measurements of both the water and the head, or at least a test drive with a thermometer in equal conditions Someone in the comments ventured some assessments.
If I had the cool head by pro design and I had 18 CC domes can I change them out and put 21 cc domes so I can run pump gas or do I have to change out the whole entire cool head in order for the 21 domes to fit ?
El modquad es el mejor por que viene en una sola pieza y puedes usar los birlos originales y los otros vienen en dos piezas y tienes que cambiar las birlos originales y existe el riesgo de poner demasiado torque y romper el cilindro
