Question: LLY / LBZ Head difference?

[WisconsinHick1]

Alright I just bought a set of LLY heads or so I thought. Turns out they are LBZ heads.

How much of a difference is there between the two? Can I use the LBZ heads on an LLY?

Yes, and you can use either LBZ or LLY injectors. On LLY heads you are stuck with LLY injectors unless the bore is opened slightly.

Russ do you have to use a larger o ring on the injector? are there any clearance issues with the tip? I asume the lbz coopers would need to be used?

I use a slightly larger o-ring to keep the injector centered.

just use a bigger o-ring, thats all you need to do.

LLY/LBZ/LMM copper injector washers are all the same.

Thanks for the info guys. We did bigger o-rings and LBZ glow plugs.

Yup, just like everybody says
