Changing weights and centers shouldn't change park position. Your Pertronix weight picture shows the tip of the flats on the outside of the weights. If a tip is touching that would keep it from returning to park position. In other words it would use up part of the advance.
pic of yours and then a pic I've got of a factory HEI and a china HEI. Note the flat side tips are on the inside of the weights in park.
Oddly enough these china weights work slick as can be. Trying to measure by hand it appears they'll go right at 12° max at the distributor. That's with full weight sling and weights hitting the stop in the rotor button. Didn't look to see if the slot was bottoming out.
