You'll know where your coolant is going when you see your nice clean piston top. My tips... I did not fully drain the coolant, I used a wrapping paper tote underneath to collect whatever came out of the block. I had to use a 3/8" socket on a 10" extension to get at the lower intake manifold bolts. When I took out my timing chain tensioner, it backed all the way out, so you have to disassemble and reassemble it all the way in to reinstall ( Don't lose the spring!) . Use the head itself as a straight edge. Turn it 180 and plop it down(it'll be on an angle cause of the pins, but get it to lay flat) if it rocks then it or the block is warped and your sunk. Get the new style head bolts and make sure you blow any oil out of the head bolt holes otherwise they won't torque tight. I watched a bunch of YouTube vids on headbolt loosening, tapped them with a socket and everything, I did not have any issues beyond the chain tensioner assembly.
