@siteunseen good call on the FPR! When I took it off, the return line was completely dry so I knew right away something was amiss. Anyway, swapped it out and rigged my old one in place and it runs. Granted, doesn't idle on its own but I can hear there is a misfire so it's probably just an injector, plug, or wire. Ill diagnose that once I get coolant in the car and be able to have it run for more than a few seconds. Once I get the rpms over 2k it sounds good albeit a small blip here and there. The other bad thing is I just have the headers on it so it's loud as all hell. I might try to rig the old exhaust up for the time being so I can at least listen for leaks, etc while I fine tune it. I'll swap out the FPR with a proper set up once I get everything back together.
But thank you so much for that small piece of input! So invaluable. I was ready to tear the head apart again to check that my timing and valve lash was on point! And thanks to everyone else for providing all the input to get me where i am, I appreciate it a lot!
