Teddy,

 
for (new i=1;i <= MaxEntities; i++)
{
if (IsValidEntity(i))
{
GetEntityNetClass(i, String:strClassName, 64)
if (strcmp(String:strClassName, "CObjectSentrygun", true) == 0 || strcmp(String:strClassName, "CObjectDispenser", true) == 0 ||strcmp(String:strClassName, "CObjectTeleporter", true) 
== 0)
{
//Change the ojbects's health
SetEntData( i , FindSendPropOffs("CObjectSentrygun","m_iMaxHealth") , GetConVarInt(Cvar_MaxHealth), 4, true );
SetEntData( i , FindSendPropOffs("CObjectSentrygun","m_iHealth") , GetConVarInt(Cvar_MinHealth), 4, true );
SetEntData( i , FindSendPropOffs("CObjectSentrygun","m_iAmmoShells") , GetConVarInt(Cvar_AmmoShells), 4, true );
//SetEntData( i , FindSendPropOffs("CObjectSentrygun","m_iAmmoRockets") , GetConVarInt(Cvar_AmmoRockets), 4, true );
 
}
}
}

The loop your using there doesn't set the other items. Your finding them, but then your only setting CObjectSentrygun?
