    Same but the AEB has a little bit of metal on the side that has to be machined off. Also be careful with the ADR as they arnt all largeport, some are smallport.

    Also, ADR's have different cams and the exhaust valves arent sodium filled, so you'll need to either buy some or swap the valves from your existing head.

    Not all AEB have the extra metal.. shouldn't stop you buying one but something to factor in when you buy...
