i doubt the h23a1 with a h22a head is going to make 220 HP at the crank.
it ends up being about even with the h22a motor power wise. and the reason for that is obviously the wonderful h22 head.

honda sold this engine in the accord wagon in like 99-00 (i think?)
jdm only of course...went by the engine code h23a
it came with the blue valve cover stock.

the main reason i would not do this hybrid is because the h23a1 doesnt rev nearly as high as the h22a stock for stock...given...the h22a head changes that...but having blown the #2 CR bearing on my h23a1, and knowing of several other h23a1's that met the same fate...i would either buy a h22a longblock for dirt cheap and use your h23a1 tranny or buy the h23a outright, instead of putting a h22a head on your h23a1.
