So I have Brian Crower 272 cams in my b20 with LS head and Crower springs and retainers also! But my question is, is my valve lashing going to be any different from stock specs? Because I can't find anything on if I need to adjust them any differently some input would be greatly appreciated!

 

it's on the website. and they don't make 272s.

 

Any time a cam is replaced you must check the base circle diameter by checking the lash. Failure to do so may result in damage or excessive lash which may produce noise.
