Would anyone like to trade heads?

Interesting.. Do you have any flow numbers on the stock magnum head? I imagine with the stock 1.92 intake valve its a bit better than the stock J head. Also I like the idea of the chamber shape on the magnums.

Check out Hughe web site they have some flow comparisons:

The engine quest and RHS head are better quality than the stock magnum and not prone to cracking between the seats.
