After reading up on the best spray bombs here on Moparts, I bought a case of the Duplicolor 1622 for my '71 GTX'x 440. I sprayed a set of valve covers after I had them hot tanked and then scuffed, along with a coat of Duplicolor high temp engine primer they look great! Not too dull, not too glossy... The can I used was sooooo much better than the old MP crap.
