Who all has done 1997 ej22e heads on the 1999 dohc ej25d? I am about to do this and have some questions. I know it can be done and boasts high compression. I'm just curious as to what all I take off what motors. I have 2 complete motors (ej25 has a seized cam and ej22 has a rod knock) What would you recommend purchasing and replacing when doing this swap. I am basically looking for a list of things to buy and what to take off each motors as I approach this swap. Maybe I'll even take notes and write up a diy for future reference.

Things I think should be in the list.
OEM 2.5 head gaskets.
OEM valve cover gaskets
OEM 2.2 timing belt.

Any seals I should replace? Idler pulleys? Water pump? Oil pump... etc. Any help is appreciated, links to threads etc.. thanks in advance.
