There are a few problems with this combo.

1 - H23 pistons are 87mm and F22 block is 85mm.

2 - With the combo you have the pistons will stick out the top of the cylinder .022" and the stock headgasket is only .026". That is a little too close.


It looks like you are using F23 head, F23 crank and rods then why not just use an entire F23 motor. Also, the Vtec on the F23 is a little different then other single cams.
