Info: Diffrences between LLY, LBZ, and LMM

[MAXX IT OUT]

I have been looking at doing an LLY swap, can I use LBZ or LMM heads instead of LLY? I have heard of people putting LBZ injectors in an LLY, but I am not sure if you can put an LLY injector in an LBZ head or LMM. Also will valve covers and high pressure full lines from an LBZ or LMM work on an LLY?

LLY Injectors will fit into a LBZ head without modification, a LLY will require some work to fit LBZ injectors

check out that thread

LLY injectors fit into the lbz/lmm heads, but not vice versa

That good, anything on the Fuel fuel system? I am guessing that the valve covers are mostly the same?

Bumping this up, Are the High Pressure Fuel lines the same as well as the valve covers?
Okay I found out that the High pressure fuel lines are not interchangeable, but together will they work with each others injectors?
