A k20a2 and k20a3 block is the same casting. The k20a2 has the oil squirters installed, the k20a3 does not and just has the untapped bosses.
Swapping the head over IS a painless task. The k20a2 oil pump is a non issue as long as you have its windage tray, oil pump chain, and oil pump chain guide... as the k20a2 and k20a3 use the same oil pump tensioner.
What pistons will you be using?
