OEM style valves - SBI vs Melling
Hello everyone. I have a Melling v0548 valve and an SBI 00548. I have noticed there are some differences between them.
The SBI valve has a step on the underside of the valve head, and its finish is different than the Melling. (SBI on the left, Melling on the right in the first and second pics)

I also noticed the Melling has a fatter margin and a wider seat surface than the SBI. My question is, would it be worth it running one over the other? Or I could go either way without much difference? The main thing that’s throwing me off is that step on the SBI which seems to me to be the biggest difference. I’m thinking it’ll be a sharp edge in my combustion chamber. Don’t know if I’d like that.
