these are both 'supposed' ej20g heads, but they look a lil diff.
what is diff?
Pros? cons? for my dohc conversion?

im a noob to shimmies and buckets overs and unders.

First pic is from an Impreza EJ20G.

The second pic is from a Legacy EJ20G.

The Legacy is an older design, with a larger cumbustion chamber. The Impreza is considered better, and has better parts availability.
