I have done a search and couldn't find any answers to my questions.
I'm getting ready to have some head work done and I want to make sure the shop is doing the right thing. I've heard that flow can decrease by using the wrong angles on the seat.
Does anyone know the best 3 angles to use for the Zetec head?
What width should be used on the valve face? Should it be .060 or .080?
Any help would be appreciated. Or maybe a reference to an article about Zetec heads.
