yes they are open deck but all you need to do is get the re-sleeved and end of story....
The 93-95 h22a1's have small crank journals than the 96+ blocks..i for one would rather have a 96+ block.......
check out the September 2003 HCI (hot compact imports) mag they have an h22a4 that is booted and has 725 WHP with the bottle...i think without the bottle they had 550 WHP..

If I put a H22A1 in my SH , I'll have to change the harness, ECU and the tranny, without talking about my cluster, so I'll rather keep my H22A4. But what can I do to higher my torque without having problem with my ATTS ?

atts works on obd2... you can not tune on obd2.... you can by a "plug and play", but it's not gonna work like you want it to. i went obd1 (p28) forget about the atts system just get the car tuned. if you don't it's not going to last for long
