Head porting shouldn't affect starting. Have you verified there is fuel getting into the cylinder is my question? This all sounds like EWS to me. Did you take a plug out and see if there is fuel on it? You should have a ton of unburned fuel on it if the EWS is not out of sync. I'm not sure if I read correctly whether you had already verified fuel or not.

I've pulled all the plugs, they all smell of gas strongly. I randomly tested 2 plugs for spark, though my dad wants me to test again with my 8/0 jumper cables to ensure there's ground for days.
My wideband O2 says AFR is 7.98 while cranking and 22 while not cranking.
I did the EWS delete from MS4x.net, flashed ands verified the bin file. I don't know how to verify it on the car. It acts the same sob umm hoping I've eliminated EWS. The car isn't even trying to start right now. I would using starter fluid that was a mix of hexane and ether, and my front fuel valve turned off. I can't crank it and spray starter fluid art the same time, plus I'm Leary of that since it caught fire last time after a loud before out the intake.
I'm sure I have a sufficient amount of unburnt fuel in my oil too. It had fresh oil in it but once I get it running I'm going to change it again.
