340 or 360?

What's the purpose of boring it 0.080"? Wouldn't that cause over heating issues? I believe in only boring a engine enough to clean up the bores. There's article's on people running 1.925" intake valve's and port work that give just as good or better flow numbers than people who use 2.020" intake valve's. Attention to bowl area is important.


There is more to cylinder heads than flow. Flow numbers are pretty low on my list of important things.
