Bad Block? What's wrong?

[USMC302]

Ok, here is the deal, I restabbed the dist, double checked the firing order, all was correct, engine runs 95% smooth at idle, no smoke anymore(original Problem) but when I try to drive it, it has no power at all, I mean i can crawl down the street in it but nothing when gas is given, engine revs but no power, sound like no compression to me. I did not get to do the compression test, out of time and money last weekend but talked to a mech that said it could be the ring gap. I didn't measure the ring gap when installing the new rins, I did however stagger them. Do you guys think that the ring gap( we are talking thousandths here) would be the cause of all this? i mean the guys from the parts store said they were ready to go. I don't want to pull all of this apart again to measure ring gap ya know?!
