What would cause this spark issue at the plugs?

Ernie Vitucci and shew01 have good suggestions that I would follow through with.

Where's the electrical problem. He says he has spark to all cylinders in post #1. I still go with what I said in post #2.

FOLLOW UP:

Redid compression test, this time with warm engine, throttles (2 carbs) wide open.

This is with a 4.2 head, spark to all plugs, only runs off of 3 and 4, with 1 and 2 disconnected makes no difference.

To me, this still does not answer the issue with 1 and 2.

D W LEAK DOWN TEST
1: 59 61 15% no leaks
2: 50 51 35% no leaks
3: 61 66 67% big intake leak
4: 60 61 65% exhaust leak

Row 1 is dry compression
Row 2 is wet compression
row 3 is leak down test
