Im trying to make sure all of ducks are in a row so to speak. I am installing a cam kit right now and I dont want to miss anything.

MS4
springs
retainers
pushrods
new lifters
Melling 10295 high pressure oil pump
double roller timing chain
harmonic balancer bolt
all gaskets needed
oil and filter
spark plugs
assembly lube

Am I missing anything?

 

Looks like you have every thing under control. Don't forget coolant.

 

Also when you get every thing back together leave the plugs out and roll the engine over several times with the timing cover on and then pull the cover back off to make sure the double roller isn't touching the cover.
