I like mine.... I took them apart and inspected them but really found nothing at all. You can go to my youtube channel and see my home inspection of SM heads, and the installation on my car. You can also find my home porting of 318 heads.
Did you put them on a stock compression 318? Did you have to do anything being that they are 65cc heads?
Well at this moment before you even replied to my comment Ive been watching your videos! talk bout coincidence.
I'm looking at the port work you did on stock iron heads.
