Default EJ22t head gasket and piston protrusion?

i've done searches over the past few days and can't find a definite answer. does anyone know from first hand experience if the pistons on the stock ej22t exceed the deck hight? i found an old post of xephyr saying it protudes .020-.030 inches. can anyone confirm this? also has anyone experimented with the phase 2 ej22 headgasket out of the MY00 NA ej22 matched with SOHC heads on the ej22t bock?

The pistons do protrude ever so slightly, but the thickness of the headgasket and the timing of the valves are such that you'll never run into clearance issues. I am personally running an EJ22t with MY98 DOHC heads and am aware of others running with Phase II EJ25 SOHC heads and Phase I EJ22 SOHC heads.

it's not the timing of the valves, it's the shape of the piston.

If your worried about do what Wedge and I did and get a thicker headgasket, i.e. Cometic.

I'm not sure what you mean by, 2.5 sized pistons...

You do realize you can't bore the walls of the 2.2T that much, in order to get EJ25 pistons to fit.
