I would put the stronger thick part down as long as it clears the block at all lift points
My thinking is the weakest point is the narrowest point on the shaft, I think the pushrod is angled more at the liter than it is near the rocker arm adjuster
Didn’t take any measurements the other night but at a glance fat side down was closer I”ll check over the weekend.
My tight spot is at the block at the deck when on the base of the cam lobe. Once it starts lift it moves away quickly . This pr is intake and offset , 7/16 to 3/8 taper, And just over 10” so trying to not go down in thickness. Could grind the block some but was hoping not to .
Thanks for the help, G
