Default Will an LS B18 head fit onto a B16a Block?

My buddy asked me to post this up for him, he has a b16a complete block he just purchased, but has his integra with an LS thats boosted. he just got done rebuilding his block on the LS due to cracked ringlands before he purchased the B16a block so he was wondering if the LS head will fit onto the B16A block so he can give the whole setup to his brother and he will still have the b16a head for his B18 block.

To put simpler just basically swapping both heads with each other, we already know what needs to be done to put the b16 head onto the LS but didnt know if their was anything that needed to be done to the B16 block to mount the LS head.

Thanks in Advance!

the car the b16 block with the b18 head will just be a beater that his brother drives, he just wants to know if it will bolt on and run without much cash, dont care about the power whatsoever. he bought the b16 engine really cheap mainly for the head only but now he would like to give his bother the leftover parts basically. is it possible without much modifications?

I've always wondered about this too, everybody knows someone who either has a b16 bottom end or a b18a/b just collecting dust. Plenty of those to be had for cheap, b16 with the non vtec head wouldn't be superior to other b motors, but could be cheap and fun regardless.

One problem I can think of immediately is the dowel pins.

Ls head on a B16 block would in essence create something <u>like</u> a ZC. Which unless boosted is pointless and is not something you want to build. Might as well go to a junkyard and pull one for like $50.

yes its a d-series

yes the head will work but gotta plug the block like you plug the head for ls/vtec
and you have to run a oil line to the head like you do for ls/vtec

he's gonna need some sort of custom head gasket to fit the head on the b16 block. dowel pin alignment issues, oil return issues, coolant passage issues...too many small details that might cause a lot more problems later on. not worth it in my opinion.

Plug the VTEC oil hole in the block, get GE dowel pins, use a LS headgasket. Better if you can drill the dowel holes in the block, but the GE's will work.

just so you know, putting a head that flies apart at 8500 together with a block thats asleep until 7500 isnt going to net any impressive results. the rockers will be popping off before the crank wakes up.

hes just trying to not spend any money it doesnt look like he wants it to be fast by any means just a simple throw together to give away thats it. basically 2 parts that nobody uses to combine to give to a brother thats all. make sure you tell your brother or who ever thats getting it thats its really fast!!!

with 404 cams, DIY head work, compression [by milling or one layer HG] you could build a respectable engine for cheap. it will be rev happy for sure

wouldnt you use a b16 head gasket??? JW. and what about head studs wouldnt you use LS head studs
b16 block
LS head studs
B16 head gasket
GE dowel pins flipped upside down
b16 timing belt
plug the oil passage on the block. what else is needed. Theres no external line that is needed.
I know on an Ls/vtec you use the Head bolt/studs for the head you are using, and the Headgasket is for the block you are using am i correct.
