Hey you for got one. Lol indy cylinder heads makes a single plane for magnum heads. I have one on my 2000 360 magnum. I lucked out and bought mine for $300 shipped brand new. I think they are over $500 now. At the time I was wanting to buy a mopar m1 magnum intake. But every one I found was listed for $600 or more. So with that said I hope the OP gets his plates made. Best of luck to the op
