Fast burn the same as lean burn or found in those with the lean burn ignition ?
Where would I look for identifying marks on those heads ?
You said milled to 59 cc , so what was it before or about what in thousandths was remeoved ?
Will the stock 273 single plane 4v intake port to match to them fairly close ?
Too many questions ?

I don't no the cc before the mill or how much was removed. BJR Racing rebuilt these heads and milled them down. So you could PM him and find out the work done. He cc'd them after they was milled and it was 59cc. I also used the thin Mopar Performance gasket to kick up the compression some.

The intake deal is just as fishy mentioned.

My heads have a big "1" on one head and a "2" on the other around the exhast side area. But other than that you'd have to look under the valve covers for the casting numbers.
