More Small Block Questions

When mounting pistons (flat tops) is it worth putting them on "backwards," so to speak, like you hear about the bigblocks?

I have fed mog/sterling 285NP's and they have the notch in the piston that lets you know which way to put the piston in.

Also, I have a hydraulic cam. What pushrods do I need to run 273 adjustable rockers with it?

Okay, one more. The deck height on a factory 318 is supposed to be 9.6".
How can I get the piston to deck height without assembling the rotating assembly? Stroke is 3.31", Rod is 6.123", and piston comp height is 1.72".

Any help is very appreciated!!

on the deck height ...if you dont assemble the engine...you can only guess at where the pistons will be in relation to the deck since the deck height on a factory engine will be all over the place...now if you take the block to the machine shop and have them square the block...then by doing the math on your crank...rods and compression height on the piston you will be in the ball park...then again....unless your rods have been blueprinted..and the crank has been index and stroke equalized....there will be some variations...
