Looks like AVCS is the easiest way to tell on the '01+ (v7, v8): https://en.wikipedia.org/wiki/Subaru_EJ_engine#EJ207

Looks like I have AVCS, I have the bump by cylinder 1 and 3. I also have taken the AVCS sensor out of the way to get to the injectors but I never knew it was an AVCS sensor. The sticker on the timing belt cover has deteriorated so I can’t get any info off of that. So judging by the fact that I have AVCS, it’s a good guess to say it’s a 207??

Ok so I’ve got something else. Right under my drivers side fuel rail. Pretty sure this is the heads, is stamped S20V. And so far from my research it’s leaning toward Ej207 but still unsure
