Ran lean, burnt gaskets, scorched pistons... ideas?

Thanks bud. Ran the codes and only got a 31 and 85 which is alright cause I have all egr/smog deleted. And since the computer doesn't give us any info I'll be going around and checking all voltages manually. Hopefully I can find something, if not I got a fp gauge I can hook up. I'll set the timing at 8* and try again. If it keeps persisting, well, I guess I'll look to get a chip burnt.. all I can do.

Default gaskets

Holy crap, they are blown. What head bolts are you using? I too have never seen a pair that badly blown on N/A car.
