Remember to use some assembly lube on the cam bearing surfaces and lobes to prevent a dry start up. It's good to take an oil squirt can and squirt motor oil on any moving parts too. Like the timing chains and guides, cylinder walls, rocker arms, etc.... I would leave the crankshaft position sensor unplugged and just crank the motor for a minute to get the oil pressure up and oil cavities full, before actually starting the motor. Leave the sparkplugs out until you get the heads and timing gear back together to make it easier to rotate the crankshaft by hand to make sure timing is correct and there's no piston on valve interference issue. Then install and properly torque the sparkplugs. If you did not pull the drain plugs out of the sides of the block before removing the heads, you may very well have coolant in your oil pan, and this requires an oil change before ever cranking the motor. You don't want to introduce coolant into the oil passages. Drain the oil, and if you do in fact see water (it'll come out first before the oil...) spray some brake cleaner into the oil pan after you think all the oil is out, just to help flush any more water out. The brake cleaner will quickly evaporate and won't affect your new oil. I might've missed it in your previous posts, but I Melling High Volume oil pump upgrade is highly recommended too.

Thank you for this. I did plan on an oil change and you touched on some things that I was going to ask and also things I would not have thought of!
