Earlier I talked about using 14014416 heads on my 84 vette.
Well now I def have to cause my 3998920 heads that came off the vette one has a crack in it. I am going to switch out the valves cause the vette valves are bigger than the 416 valves. Do i have to modify the heads to switch the valves???????
