Fresh valve grind on marine 7.4L Mercruiser.
On #1 cylinder crank timing mark both lifters are even and slightly above their holes - push rods centered and sitting in rocker pocket.
There are Hi Performance guides under the rocker bolts guiding the push rods.
I pushed up and twisted the push rod and tightened the rocker arm bolt till the push rod stop moving then cranked 1/2 turn more.

On #1 intake the push rod stopped turning so I cranked the bolt another 1/2 turn.


then I noticed that the Hi Performance guide was still loose on the bolts and that the bolts were not seated flush, yet the push rods would not turn by my fingers.
any help would be appreciated on what I'm missing
cheers
Hank
