Lowering ?

[Rex'69]

First of all I have to say thank you for all the great info on this forum. I purchased a '69 c10 long bed one owner about a month ago. I have it down to the frame and installed 4" rear coils from cpp that came in their kit with the trac bar, shocks and relocaters. My plan was to put 2.5" drop spindles up front but now I'm thinking I may want to go a bit lower. My question is if I put 1" drop springs up front can I use stock height shocks with them? Also I would have to put a 1" block in the back to keep things even so can I use the drop shocks for a 4" drop? Also if anyone can tell me if it's worth worrying about going from 2.5/4 to 3.5/5? I haven't figured out what wheels I'm gonna get or size. Any info would be appreciated on looks or ride comfort or anything.
