Need new valves but on a budget

[Kambo]

I'm rebuilding my h22a4 and it has bent valves. I'm was wondering will it be cheaper to put a h22/f20B or any other compatible head on top? I was also thinking grabbing a head that has the same valves and using those.

most easy and cost efficient way is going to be to put another head on it
