Lower Rod Pin on 430 XC

Hi guys. I'm working on a rebuild of my '82 430 xc engine. Restored the outside and in its second race, I blew a piston. Thought I would go through the entire engine just to check the inside. Haven't had a chance since I bought.

Somewhere I seem to have read that when pressing out the lower rod pin, it has to go one direction only. Now I've spent hours hunting for this info and can't find it. Gee, don't it always seem to go.....
Anyway, if anyone could fill me in, it would be appreciated.

It doesn't matter which way you press it out just be sure to support the crankwheels. I made a press plate so I'm pressing the crankwheel off of the pin.

Here is my version of a crankshaft press plate. Worked just fine on my 12 ton press.

Isn't the more demanding thing to get it back together and put it in V blocks and put dial indicators on the ends which don't deviate as the crank is spun?

Am I significantly off in thinking $45 to $75 to have someone who regularly installs rod kits to switch a rod and pin and true?
