Strange choice by BC, at .500" valve lift there would be .220" to coil bind.

Yeah, installed at 1.640, with a .060 safety margins, the springs would be good up to .700 lift.

Installed Height and Spring rates look good but just be aware because it being a dual Valve Spring not likely it’s a drop in spring.
Not being a dealbreaker, but it’s looking like you’ll need to have the Valve Spring seat machined so it will properly fit the I.D. of the inner spring.

At least it’s created some options for stock valve Jeep heads
