318 head porting for the average joe
That's Hysterical lol...
How thin is too thin?
I guess an 1/8 of an inch of iron is desirable in a 1000 degree exhaust port.
But if you want a free-flowing port then its gonna bee possibly 'half' that where the bump is loacated?
Do you feel lucky when using a heavily ported iron head.
Or is is best to leave the bumps in place and suffer a small flow loss?
I assume the small block head has a much more superior port compared to a 906 etc?
I have fitted 1.88 exhaust valves in iron heads as per David Vizard and others info.
I would have thought a 1.70 exhaust valve would be beneficial but most say 1.65 is plenty?
