I measured and came out to be right at .100 preload which seems to be acceptable? Factory is anywhere from .060 to .091 So I hope a hair more doesnt hurt anything. Valvetrain is nice and quiet though. Does anyone know how much preload you lose on a hot motor? obviously mine was cold when I did all this But maybe once the motor is hot ill be about in spec?

 

Aluminum block probably .006-.009”.
