6.2 Oil bypass valve help

[Coal Cracker]

Was hoping someone can help me with this, I'm putting together a 6.2 and in the process of preparation for the hot tank and cleaning process I removed the oil by pass valves. I know what B C D are for, my question is for A I know it's the oil cooler bypass that has a thermostatic valve and a welsh plug with a hole in it, I need to know which way the valve underneath the plug is supposed to sit.(spring side down in block or spring side up) I've searched Tm's and the Gm parts and service manuals, to no avail. I should have taken pics like I usually do but I was rushing to get to the machine shop. Thanks

Was hoping someone had an old junk 6.2 or 6.5 laying around they could knock out the welsh plug in the filter mounting boss and see which way the valve was installed?

I have a block sitting on the shop floor, I have to pry that plug out I guess?

You don't know what it would mean to me, lol I've been driving myself nuts I've been hitting junkyard's searching gm manuals tm's Im kicking myself for not taking a pic. I have a new valve and plug from Gm. All I need to know is which way the valve is facing under the plug. If its a good block I'd be glad to get you a new plug.

Ok, on my motor, 6.2, the spring side goes up into the block when looking from below. The button/valve side should be visible when looking down into the hole.
