Big Valves and porting?

[GeneBob]

Brent, I was hoping this thread would peak your interest and thank you for adding some information. I am not trying to flow an engine for Bonneville, just looking for where the typical Model A port issues are to look for some improvement. I suspect there are some places to look at in the ports that are common problem areas.



Jim, I will look in your book. I frankly forgot to look there.


Thank you both you have valuable experience.
