didnt crower used to have a 2.2L stroker kit for the B20?
and yes...bonet still can close... coz ur modding the internal of the block... the block itself isnt changed so no diff. and u CANNOT change the height of the block....
so no problems with closing bonet unless of course u go H22A with H2B kit, then u might have issues with closing the bonet properly on an EG.
