Picture of 340/360 head porting....Mistakes?

One of the reason i was trying to keep the bowl less than 90% was because i had a small .474/280 MP Hyd cam at the time....
Even though i new these heads would never go back on anything,........ when i started poking holes in the SSR.
Actually my mind set change many time, with what i should do with these heads.

When i started on these heads, i only had air and a die grinder at work..........and a flow bench at home. So like i said i chased my tail a lot with a HMMmmm if i raise it here, bend it over here, grind this off here, and smooth it up over there............

The old saying make one change at at time.............i was making 20 and then testing it on my flow bench.:rolleyes:...:)
