I checked out the link to the 302 build. They are using aftermarket AFR heads which are the best for flow that you can get. Check out the heads comparison in the tech section of the Comp Cams website. The porting on your iron heads would have to be very very good to get anywhere near the AFRs for performance. Also you would still have to rev it hard. Do the simple thing and build a 347 - more power and torque and it looks exactly the same from outside. 347 Stroker kit with steel crank, H section steel rods, forged pistons and rings and bearings £1,100. (420hp, 430ft lbs torque. 375 ft lbs at 3,000rpm on Edelbrock RPM heads and inlet, 650cfm Holley)
Cheers
