I have a ping in my new 440 that I can't get rid of. The motor is a 440 with 452 peanut plug heads, 1-7/8 headers, 800 Holley, RPM intake,Hughes whiplash cam,Champion V59YC plugs, stock dist with mod ( but stock springs )MSD 6 AL and Blaster 2 coil

I have my initial timing down to 12 and total at 32 my primary jets are up to 79 and 81 secondary 6.5 power valve. I think the plugs I have are as cold as I can get I had to go to a racing plug to get the cold ones I have. At first I thought it was my plugs being too hot the colder plugs helped a little but I still have the ping. I think my jets are way too big but I was tinking that it was a lean ping so I was adding fuel to it but now I'm not sure. It runs pretty good but this ping sucks
