Quote: I use 92 octane at 36 degrees total timing, no detonation, i swapped to the thim sheet metal gaskets last summer and there were no detonation marks either. I'm just wondering by swapping heads if there will be 1000 dollars difference.
Depends how much money you have. If you're going hungry and the kids don't have shoes then spend the grand on something else. If you have a big toy budget then a set of Edelbrock heads is a logical investment. Better yet buy the Mopar version with the straight plugs so you don't have a hassle with the plug wires.
