Was having a go over the 1500 stocker that I have today and noted that one of the valves was stuck open. The motor has not been run for a while. I got it moving again by gentle prying and turning the engine over by hand. Seems to have freed up OK.

My question is whether this is now likley to be good to go or once they have been stuck should I strip off the head and tear things down further?

Everything has a cause Ian, you know what to do!!!
