Somehow our turbo engine has three ECG 6564 B2 rockers and 13 5751066 rockers in it! Mummert's sites state that ECG 6564 is a 1.54:1 rocker, but says nothing about B2 marking. 5751066 is definetely a 1.43:1 rocker. Houston, do we have a problem? Or is those B2 rockers some replacement ones for 5751066 units?
Ok, I found one Walt Nuckels article about setting the valve lashes, but that didn't make me sure
