Little cracks around valves on head

Hi guys

Just in the process of cleaning up the head and replacing gasket etc. Head looks good for warm, very little corrosion around top of water feeds (three little triangles). My only concern are these little cracks around the vavles. Below is a link to an album on my imgur.com account. Please could someone take a look and tell me what they think. I think they'll be ok but I am worried they might develop into bigger cracks etc.

Appreciate the time, thanks in advance.

the cracks ?

Evening people.

I have given the head a good clean, see pictures below. All seems to be good with my only concern being those little cracks. I am tempted to put it back on but to check again in another 5000 miles or so. Maybe sooner depending on how soon I rack up that mileage. The main reason for this being the lack of cash to buy a new head. Of course this decision is not final if someone were to tell me it would be a terrible idea to do what I have just said. What do you reckon?




Ignore the pen, that was for my reference.

Ive resized them. I thought the forum did it automatically. Ok, that seems to be the general consensus. *looks for something to sell*

cracks near valve seat wont be long before seat drops in piston,they are held in with 3 thou interference fit ,not much
