Did you use engine oil or assembly lube on the bearings during reassembly?
Did you apply engine oil to the piston rings or cylinder walls? It looks bone dry to me. I don't see a single speck of lubricant anywhere.

Do you still intend to use the factory thickness headgasket? .020" is an awful lot of material removed from your deck surfaces. Using a stock thickness headgasket with raise your compression ration up roughly .5 to 1 putting you back to the factory 9.5 to 1. Not a big deal but it defeats the purpose of using lower compression pistons.

It looks like the pistons will come awful close to smacking the quench areas on the head. Doesn't hurt to measure piston height. At TDC, are they sticking above the block deck surface? A thicker headgasket will remedy all those issues.

Have you figured out why the valve bent? I'm guessing valve float? Test the valve spring (better yet, replace it) before putting it back together. Reinstalling a fatigued spring will cause more bent valves.

Thank you for the reply. All those points are great and they too are ones I'm thinking about a lot doing this build. I did use assembly lube on all bearings; I like to clean off the lube on the parts it doesn't need it. The pistons do not stick out of the blocks deck surface at all and yes I do plan on using stock thickness as I'm using the felpro gasket.

Honestly couldn't tell ya. This s14 head is off the motor that is in the bay of the s14 right now. I purchased the car (s14 rolling shell w/ blown motor) about 2 months ago. Check the pictures up top.
