Do domed KYB 399’s interfere with 302 cast heads?

I get what you’re saying, I have other heads I can use that I’ve used 399’s with before I have 302’s and was to see if they’ll fit or what material would have to go to make them fit as the measurement of how far they stick out of the block it fine. It’s the center of the quench pad that I’m worried about. But I’m curious. My main questions was if they interfered, just in case anyone knew from experience. I can make pistons at work we do all the time but asymmetrical domes aren’t easy to make and making all 8 for my own car so not getting paid would be rough. Also I need to go look at part numbers as the 399’s aren’t the only pop ups I saw just the only ones from a brand I’ve used successfully literally hundreds of times now.

Now here's the 318 dome you plan to use. Not even close to the same. All we're doing is trying to be the voice of reason and advise you to be SURE, instead of doing something "just because you read it on the internet".
