Thanks Grumpy,
I will revisit the valves, yes, I think maybe valve is sticking in the guide.
Not much to mow here, so I will give it a good run at some point.

I've got the idea now, with how oil enters the rocker area.
This head doesn't have that hole, the holes are for locator pins, so it must come down the push rod tunnel and then the hole in the bottom of the plate pictured. Which I didn't notice until your explanation.
