Better retard your timing and run premium gas. Your compression readings are pretty high.
what he said. try 93 octane and back your timing down to 36* total at 2400rpm. Also unhook the vacuum advance. You could be advancing up to 50+.

Yup, absolute highest cylinder pressure for me is 185psi. and with that and iron heads, you need to be spot on with your tuning. Make sure the curve is not steep, it needs to be gradual, and your fuel curve and carb tuning need to be very close. When you get those right, it will go away. You will need to run premium unleaded... 93 or better.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

On Mopar 7 1/4" diameter balancers, if you measure 2 1/4" in the advanced direction you'll be at 36 degrees advanced.
I love the smell of Deer guts in the morning, it smells like... VICTORY!

Let my try this one more time just to be sure. I need to make a new timeing mark on the balancer 2 1/4 inches clockwise from the orginial mark and bring the new mark to the "0"on the timing plate? I must be a little slow and just want to be sure I understand before I blow this thing up. Thanks, Alex

Alex you are doing fine. We are here to help each other out & I get helped here every day in one way or the other . Standing in front of the car bending over looking in, make a magic marker mark 2&1/4" to the right(clockwise) from the factory Line. this is about 35.5 degrees which would be a good starting point for you to set TOTAL timing & do this with vac advance DISCONNECTED & plugged & the eng revved up to ~2500 rpm or so to where the dist weights are fully advance as far as possible (in other words it wont advance any higher). lock down the dist & for reference see what this puts your initial timing at when you go back to idle, reconnect your vac adv & take her out & see if you hear any "pinging".this is the rattling that you are hearing when you accelerate that sounds like a bunch of marbles being shaken in a tin can & it is VERY damaging to an eng & must be stopped QUICKLY. EDIT I reread your post & yes you want your magic marker mark to be at the "0" on the timing plate.
