2.0/2.2 head on a 2.4 block

I just wanted to verify that this WON'T work. Does anyone know for sure?

That's correct. The mating surfaces are different for the LE5. The L61 and LSJ are interchangable. They have used LSJ heads on L61 blocks in racing engines for some time now.

Ok thank you

They've also used L61 heads on LSJ blocks....with better results Just a little tidbit from my GM contacts.

I know this sounds really retarted but what do you mean by the mating surfaces are different...if this is a really retarted question feel free to flame, well after you answer lol!

so would putting an lsj head on a 2.2 be better or worse. im a lil confused

What about a LNF head on the 2.4L??

Basically no. Because youd need to swap pistons and use direct injection at that point.

Ill have an update on My L61/LE5 hybrid very soon. As in this week, ive got both heads, both blocks, both gaskets, lots of pics, and all 3 sets of valves(yes LSJ also)
