How much are 360 heads (non magnum) worth

the numbers on those heads cant be from 1970 so they have been replaced. teen heads on a 360 would make gobs of torque but would be all in at 4000 rpm. RV style. Not common but not unheard of. The 360 callout is misleading measure the valves or just measure the height of the intake port. the 318 is shorter rhan the 360 port and should be visible without pulling the head
1.05x2.07 is what a 318 intake gasket is stamped to. 1.16x2.28 is 340/360 intake port size.....post your results!
