Ok i just got this in the mail today. I am building a 4mm stroker. I didnt buy it directly from vitos,but it is brand new. Its a hemi head 2 with 18cc stroker domes in it.
Here is the problem. There is no place for the inner o-ring that surrounds the bore.There is a groove for the outter o-ring though. And when you put the dome into the head,it is recessed like it should be for a stroker,but there is nothing to hold it into the head.It wont press against the cylinder with the rest of the head. Like if i installed it right now like it is the dome would actualy be floating 2mm over the cylinder deck,and would fall down to the deck,there is nothing to hold it up. Shouldnt there be an outer rim on the dome with a groove for the 0-ring? Like a little outer ring that will go against the cylinder deck? Maybe i have the wrong domes or something.
Here is a link to my photobucket with pictures of it. First pic is just the dome sitting in the head,second pic is the dome by itself,Third pic is the dome pushed out a little bit so you can see what im talking about with no o-ring groove,And the 4th is just the dome sitting there again in the head.
My build has completely stopped till i figure this out.
