And I’m just trying to figure out why my trans stops shifting randomly. I feel so stupid when I read this thread. I cant even figure out the simple stuff.
its not like im finding anything definitively wrong over here either tho

Did the water situation ever remedy itself on the last combo? I remember you having problems but I can't remember the solution. Doesn't look like its lifting the heads and everything looks good to me. The staining in the cylinder wall does look odd but nothing jumps out as "broken". Heads look good?

Nah that's why I'm ****** with engine again...I've blamed it on headgaskets but don't know anymore...I've done head gaskets more than a dozen times and never had this many probs

Is there one single thing you DIDN'T change from the last combo? Other than heads them selves and short block

last time i changed the head gaskets while it was in the truck, thats why i assumed i just messed up with the head gasket or something.
the block stayed in the truck i scraped and cleaned up the surface
i'll take some pics of the heads, they were freshly resurfaced so no existing stains. you can see where the fire ring dug into them around the chambers a little close. but if coolant couldnt get to any one them i dont see how the gasket could have failed
dont know about this penetrating dye either.... i mean there is something there you can faintly feel it dragging a fingernail across it so dye will definitely sit in it anyway. after i throw the head on it i can try and put about 200psi on the cylinder thru the leak down tester and see if any bubbles make it into the water jacket - but thats prob still no where close to the pressure the cylinder makes running so it may not be enough

preposterous! i'll get a diff engine for the yukon.
this thing still ran fine and made a ton of power, im just burntout on the whole deal. i'll fill the block and put it in something and run it on 100% meth to keep it cool and fuggit. id pull the whole rotating assembly and throw it in a new block but then this one would end up a $3000 paper weight. rather just leave it together and use it for something
i slammed the heads on it last night with lsx gaskets and a generous amount of spray copper on both sides. torqued the big studs to 115ft lbs, the lower 4 to 70ftlbs, the ones in the valley cant really get a torque wrench on but they a whole lot tighter than the 30ftlbs it calls for. if it leaks it aint coming from the head gasket.
havent heard about tranny so who knows - will prob just throw engine back in this weekend and wait
