11/32 valves in X heads

there is a problem with changing the lenght on the valves in j / x heads.. since the stems dont stick straight up, if the valves r bit longer u will "need shorter rockers" witch u dont have.. there are these adjustable stainled rockers that gives good room for retainer and a bit grindable:

in anny case u will need to make sure that the roller dosent hit the valve stem to far out, it should be in the middle in ca half of the lift.. even if they are adjustable and u could grind room for the retainer.. incorrect geometry will make the valvetrain suffer. link below is a nice way to study it :P

hope this helps
