I have a 1985 ford f250 with a 300 bored .60 over and the timing marks on the harmonic balancer do not relate to TDC on the number 1 cylinder. The marks are aligned with TDC on number 5. How can this be?

So, ive spent the last 2 weeks either waiting for parts or having to return parts because my local auto parts store always orders the wrong thing. Only to run into problems with the finished project... Here is the run down. Its an EA82 1985 subaru gl station wagon. Recent headgasket failure ( cracked heads ) non existent choke, and possibly a bad starter, and bad breaks. So i recently bought re manufactured heads, and a weber carb, and some shiny new brakes. My subi will be perfect after this! IF i can get it running. Here is what I'm 99% sure of. The cams are timed, the distributor is timed, ( enough to start ) and in correct rotation for TDC ( I have rotated it 180 degrees as i made that mistake and troubleshooted that issue. ) I have gas ( 2.5 psi worth from the fuel line ) I'm 90% sure i have no vacuum leak from the intake. as there is good vacuum there. I have excellent compression on all my heads. ( 120-140 ) So i think i have narrowed it down to spark. Which i have, on all wires but... The only thing i have to suspect is my ignition coil reads a little under spec, and my ignition control module reads as having interference. ( which it shouldn't ) But as i have spark im not sure if that matters. The other fishy thing is that my carb seems to spray alittle gas up through the choke butterfly as it turns over. It is so close to starting its not funny. But it just wont get there. Its just not catching/starting. Please help! I'm at wits end and i need this thing running before the end of the week.
