95 EJ22 heads on 94 block?

Worth the 7 HP gain if I'm going to be in there anyway?
Purely hypothetical since I doubt I need HG's, but I'm curious to know for posterity.

The y-pipe is the same too.
Here's a pic of a 95 head:

Perhaps I just don't get how the exhaust y-pipe fits the same on a single vs. dual port exhuast head?

i have an extra set of turbo heads? if you are interested
Hhhhmmm - wonder exactly what's different about *those*?!? I'm sure the cam profile is totally wack for an N/A engine but that does always bring up the possibility of a low-psi turbo setup.... maybe with M/S
Not sure how the open-deck block would handle that. I'm sure 5 psi would be alright and probably kick out another 10 or 15 HP though. Need to inspect the engine condition - she said the oil was changed every 3000 - 3500 and she's a little old lady so probably not lying about that.

I thought the exhaust configuration accounted for most of the gain in performance.... is that not correct?
Maybe not, because from 1996 it was single port again. Maybe the difference was due mostly to roller rockers,
if they allowed to increase valve lift, but I don't know. The power increase for 1995 was 5 hp, from 130 to 135.
There was a furher 7 hp gain in 1997.

In 95 they changed the exhaust manifolds, so you would have to have your 94 exhasut system modified to fit accordingly.
IMHO the only true advantage to the 95 ej22 heads is the roller rocker design, other than that I have found no difference in them.
