Head Porting - Who's Good?

Shady Dell did my Magnum RPM's. Got their stage 3 port job plus valve job and assembly with springs I provided for $1100. He flowed them and provided me with results. Flow at .600" 293.4 intake and 205.1 exhaust. I took them with me when I visited the US and he turned them around while I was there for 3 weeks so I could take them back home with me.
