question about a head

[250rwrx]

i have a lrd 350 powervalve engine and it has a pro cross head on it does anyone know if this head has a interchangable dome in it.

[bushwesl]

It sure does.

how does it come out i tried with my fingers and no luck at all

[bushwesl]

Hmmm... It should push out. It should have an o-ring that seals it, so it might take a good amount of force to make it come out.

does it screw out out push it if it srews out does it screw counter clock or clock wise

[bushwesl]

It should just push out. On my old Pro-X 330 cylinder, which had the Procross head, it just pushed out. There was an o-ring that sealed the area that went up into the head where the spark plug threads in at. You shouldn't be able to spin the dome inside the head at all, as there is a small tab in the head that lines up with a small machined area in the dome so that way it can't spin and it can only go in one way. I don't know why you're having so much trouble with it, seems strange.
