2006 5.7 misfire issue

[N1NJ4LL0]

Just rebuilt the motor after a valve seat dropped.. New head and replaced all pistons and all the only thing that wasn't replaced was the camshaft, crankshaft, and oil pump. I'm getting a multiple cylinder misfire. New plugs and checking timing all seem correct. However tonight cylinder 3,5,and 7 have wet plugs and the rest are dry as can be. I've done the normal checks for fuel and spark and such. And I'm just at a loss now and can't seem to find the next step to try and remedy this.

Check compression and then rip your valve covers off make sure the push rods are seated 100% its happens all of the time on these during install. The intake or exhaust push rod will be half clicked in or flat out miss the hole and cause missfires since you have multiple probably a intake pushrod. Also how did you set your timing did you use the marks on the chain? its very easy to set timing on these just dont guess always use the marks oil pump has to be removed to do it correctly.
