when I pulled the engine, I found red silicone on all pushrod tube o-rings. Red silicone between barrels and the case.
Is this standard procedure on these engines? 1700cc

No this is NOT standard procedure...well maybe it is.....I see it on done quite often. But its not PROPER procedure. Get the high quality viton seals and the silicone is definitely unecessary.
The manual I have doesn't go into detail about removal/reinstallation of push rod tubes.
I read on the net that you slide the tubes through the head, and into the case...
Is this correct? I can put the heads on first, then the tubes?

That is correct. The heads go on. Then you slide the tubes in with the new seals. Be sure to make sure there are no burrs to tear your seals and lubricate the seasl slightly...again so they slide home withoput tearing. The spring clip holds them in place.
The reason people resort to silicone is because this is a extremely notorious spot for oil leaks. Typically available seals warp easily. Gary is right. Spend a little more for the good ones.
It's standard for the barrels, but should not be on the pushrod seals.
