318 build using 302 heads

Morning everyone, I will put a caliper on them tomorrow, if it is a 1.88, I will ask my buddy why he didn’t put the 2.02’s in the heads. We trade a lot of labor, I do paint and body work, he runs a machine shop. He is way more knowledgeable about that area then I am, I will let y’all know what he tells me.
Thanks again to everyone
