Hi Jake
This may be a completely bum steer, but it would be interesting to know exactly what you did when you cleaned the valves.
If you stripped everything and cleaned out the valve guides they shouldn't (!!) be the problem, but if you cleaned the valve chest and inlet/exhaust channels in the head with petrol with the valves in place the petrol will carry minute bits of crud down the guide and then evaporate leaving the crud in place.
Petrol is good at doing this. To get old engine oil well into the leaf springs I dilute it with petrol, which carries it right in and then leaves the oil behind.
I'm sorry to hear about the jobs. I'm well into retirement so the realities of life for working people tend to pass me by. Probably no great solace to you just now, but things will get better!
Good luck.
