Mancini rocker questions...

I know you need them now but just a heads up. I order stuff like this during the Black Friday 40% off sale. I get free shipping on my orders and no tax so it’s a triple win win win. Some stuff is so cheap you buy it just to have it.

when you get the rockers centered on the valve stems , try putting a .010 feeler between each rocker arm and stand , and leave them in while tightening the stands down.... works for me .recheck the line up on the stem /roller...
if that dont work , you got other issues...
