changing engines

[maykelcj]

tomorrow I'm going to get a DOHC engine for my blown neon. I 'm going to reuse my SOHC head on it. All I'm using from the DOHC is the block, pistons and crank-shaft. There is anything I should know before atempting this? the new setup will be my SOHC head with a DOHC block and pistons.
Anithing important about sensors and EGR. The DOHC block is a 99 while my car and head are a 95.
THANKS!!!!!

(and yes I know....I should go 2.4, but the thing is I have no time and no money. A friend gave me the "new" block).

Some locations may be different but I can't say which ones, as I have yet to work on a 95 neon engine. I do know some sensors are different.
