318 head porting for the average joe

Badart said
Dang those flow numbers are pretty sad. LOL. This thread will help so many guys that ask the question "Should I run my stock 318 heads". LOL Did you happen to CC them? Just curious. Why is there such a small increase in flow numbers from .300-.500, just the tiny runners?

Good to have you posting again.

Thanks man.

124cc stock intake port, chamber measured 68cc

The ports were designed to max flow under .450 lift, thats where the factory cams were, so thats my 1st idea for 'as cast/smoothed'.

Once i do the short turn & bowl work, the numbers will start picking up above where the original design intended.
