hi guys! at lancershop.com when you go to see head studs-tech tip it says that when installing new head studs you are supposed to pull the head and do the install and not installing them one by one without removing the head-is that true couse pretty soon am gonna be ready for a new cams and i wanne do it right the first time

 

depending on what cams you are getting you will dont have to have head studs. but to answer your question, the correct way to install them is by pulling the head. by installing them 1x1 you run the risk of having a leak

 

i'm thinking about cosworth for evo9 cams but nobody sell them,am i missing something here,what the heck happend?i know they were on sale last time i've checked

 

here they are at machevo.net http://www.machevo.com/cocaevoix.html i am not sure if head studs along with valves springs/retainers are recommended for them or not
