without needing to be technical about anything else needed for a roller rocker change, please let me know what i need to do (no need to explain other stuff like springs, rods, etc.) to go from stock to 1.6 rockers?

is stock 7/16 or 3.8 or whatever and what is needed to go either way?

 

well stocck rockers are 1.6 1.7 is the upgrade and there pedestal mount, usually 3/8 or 7/16 sizes are for stud mount pedestal mount ones are all the same size, and if you want to upgrade just get the cran pedestal mount 1.7 there cheap and oe on cobras and all you need is some silicone for resealing the valve cover gaskets and some oil, other than that and the rockers you dont technically "need" anything.
