So took my head off cause left cylinder wasn’t firing and when I did leakown test I found that the left side I take valve was leaking. It’s all apart now I lapped the valves as well and cleaned the whole area. I put water On the valves let it sit for a bit. I come to check it and there’s leakage detected o the intake valve. I’ve lapped it twice now didn’t work. I have about 3 other heads in my garage this old dude gave me a bunch of xs parts. I switched the valves and spring itself and still leakage. So I have 2 questions. Is this the proper way to check for leaky valves? And what else can i do to besure the valve seats correctly?
