They are 35 lbs heavier actually... In an EG, this is generally true that u wont notice a difference... But in an EF, you would notice a difference... Lets not forget, that our stock EFs here in the U.S. didnt have the B16 stock, and the suspension isnt built for the heavier engines... Well if the B16 is about 30lbs more than our stock, this is fine, the suspension can handle it... But if the H22 is 35 lbs more than that, thats a total 65 lbs, in a car that was designed to handle a much lighter load... So regardless, if u drop in an H22, you will need to upgrade the suspension, as well as the brakes... Plus understeer is not 100% a weight issue, it is also a power issue... If u have too much power entering a turn, and just enough weight to make the momentum, you will have problems...
