Valve sticking
so ive got the valves for piston #4 on my 22re sticking to the point where the piston will un-stick the intake, i just had the head resurfaced and i was wondering if the hot tank would have anything to do with that?

If you just had the head off and hot tanked, I doubt SeaFoam will help your problem as you shouldn't have enough sludge or carbon buildup to interfere with valve operation that fast.
What else did you do to the head? Sounds more like a mechanical interference issue to me.

What do you mean the piston will unstick the intake?
Did you have engine and cam positioned at TDC when you installed the rocker assembly and tightened the head bolts? If cam and pistons were out of sync you may have bent a valve.
Did you align your timing chain with the marks on the cam and crank sprockets?

ya i alighned everthing up and all that jazz and the psiton will come up and give it enough force to un-compress the valve spring (with valve cover off and manualy cranking the engine) or i could take an extension and tap it on the spring and it would also decompress, ive been told by my fasha to use some carb spray on it and crank it by hand then spay it and repeat a few times but i still dont know

For what most shops charge, its well worth having a machine shop inspect a block or head(s) any time you pull them. They have the right tools and tons more experience than most do-it-yourself mechanics (including me) can hope to.
Once you find a good shop they are worth their weight in gold!
They do a much better job of cleaning them for cheap too!

here is the bad valve can you see whats wrong?
Here is a good valve for a hint
The stem seal isnt where its suppose to be
Can you see which is the bad valve (the right one)
and its kinda hard to see but there is a small dent in the top of the piston from the exsuast valve (spelling i know)
