Valve springs for a 318 stock?

[Mopewbie]

Hi all, help again please.

My car is a 318 stock (as far as I know).
Originally 2 barrel, now 4.
I believe I finally managed to track the ticking issue to a weak spring (I car turn it by hand and the rocker has some movement)

(Lifters are new, all rods were checked and are all same height and not bent)

Anyway, which one of the following options should I order?

I'm attaching pics of the block info as well.

Thank you.

Melling VS150 or Qualcast 32672 are very close to the factory stock 318 springs. Are you planning to change just the one spring?
If it were me, I'd order a full set of 16 springs and replace them all.

Yes, I what want to replace THAT one for the moment to give me the piece of mind of finally have found the noise.

But definitely replace the whole lot in the near future.
I just had the engine apart to replace the gaskets, I even did the lapping on all the valves but I had to rush to put the engine back and didn't check possible spring tensions. (Wouldn't make any difference since I couldn't wait for new ones to arrive anyway).

So fingers crossed that is the issue, then I can do one by one, or remove the head again.

What I really want to do is to check the piston rings as well. Ideally having the engine out and paint it.

When you replace the one spring, let us know if it solved the problem.
