318 build using 302 heads

Good morning everyone, I just checked the heads, they are 1.88, / 1.60. I talked to my buddy, he said he could have done the 2.02 valves, but it would have not have made big difference in those heads. He did also say, those heads are prone for cracking between the valves with the 2.02. Both of these points were made in this discussion, that says a lot for everyone here. For what My son and I are View attachment 1715609809 doing with the heads, He said we are on the right path, he did assure me that all the port work was done correctly, and the right way.
Thanks for all your input and experience. That is how we learn. I’m trying to load a damn picture, sorry
Did he tell you he put 2.02 valves in knowing they were 1.88s?
