if im not mistaken u just cant put k20a2 cams into a accord euro motor?

wouldnt you have to do a head swap?

k20a2 head will have provision for the third cam lobe. on the k20a2 head both ports are open, once vtec kicks in the valves are opened longer

where as a k24a3 head vtec machanism does not carry a third cam lobe and only opens up a second port when vtec is engaged

please correct me if im wrong but from what i have read, this seems to be true
