Do I need a solid lifter?

Need more help here. I'm installing a Howards hydraulic Ratter cam in my 340. I need to check my valve to piston clearance and get my pushrod length figured out. I have decked the block for finish so I could use SM closed chamber aluminum heads and Crane roller rockers that came with the engine. The pistons have been machined to zero deck height and I am using .040-.045 head gaskets with L-2316 thirty over pistons. Short of buying 1 solid lifter to check this does anyone have another idea? The Howards lifter has a seat height of 1.892. The closest I can find on a mechanical lifter is a comp cam solid with a 1.880, close enough. I know pushrods can be had in .050 increments. I just don't want to wait another week and spend $70.00 on a one time use lifter. 20240319_050458.jpg
