the K20a3 is the low rev, thin rod low CR engine that comes in the 02-05 civic si and base rsx, the head is commonly known as "fake VTEC" very similar to the K24a4 Accord/CRV head but it has a smaller combustion chamber which promotes better economy, you can get them for basically free. putting an A2 block which is known to survive 600whp under an a3 head bumps the a2 compression to 11.5:1 but when I tell people the combo they get physically sick
