Put the problems with Coon aside, has anyone ever compared a set of Coon's SOHC heads with Pond's SOHC heads? Is there a superior head? Not talking business practices, personalities or any of that. Just straight quality and performance of the head. I think Coon is the only one who flipped the D shaped exhaust ports upside down for better flow. Can the Pond heads be ported for an oval exhaust port shape?
