Someone asked so here it is. I thought it was common knowledge.
These are 45 degree angle cut NOT 35. 35 has better flow? does it? I know nothing. But would like to learn more. How about 30 degree? Why is this? Swirl pattern? Is there an intake swirl pattern to speak of? What sort of flow work would one recommend for a wee sport scout. Smooth out the intake manifold? open it up? cut/trim the exhaust guide? Open it up? Longevity VS effect? Is it worth it?
Pop-up piston, squish band? upper head pocket fill? Anyone messed around with this? Has anyone done any flat head flow port testing? Ultimately, does it really matter?
