David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

Go ahead and calculate how much it will cost to even find someone competent to port and prep those 302 heads, and come back with the cost. Jesus this stuff ain't rocket appliances!
I had no problem making 240+ cfm. This guy is already @ 220 cfm with a stock size valve. I think all these cheap Chinese heads has made you guys lazy.
