Very COOL truck Dave_J.

So, if I'm trying to avoid detonation, would aluminum be better than stock magnum heads? Or, is it about the same as long as the heads have closed chambers? I have done some more research and read some threads that say tight quench lowers chance of detonation. Does quench just work on lighter vehicles, or could quench work on a heavier vehicle like mine as well. Also, do y'all know/have any experience with Huges's cams? I'm thinking about calling them for a cam.

Thanks for the responses
