Re using cast iron rings?

I'll get killed for this, I say go for it. Learn something, the acquisition of knowledge is not with out effort; when done you will know with certainty if it can be done. As already stated put the rings back in the same hole they came out of, think "how does a ring know it came out of it's cylinder?"

Food for thought........years ago in "Car Craft" magazine, Jon Kasse (sp?) did a test of what makes more power, Hemi or wedge, he used a 460 Ford as his base because it can mount Hemi or wedge heads; when he switched from wedge heads to Hemi, he had to change pistons due to chamber shape, he moved rings from the wedge pistons to the Hemi pistons also. Love , hate Kasse (sp?) if you like, I think he has won more Engine Masters than any one posting on this board ( I could be wrong ) so I would think he knows something.

BTW the Hemi made more power
