lash caps for eddies and crane rollers

i have the La style eddies with the 1.5 crane rollers. my roller tip is a little to close to the exaust edge. i believe i need lash caps to correct the angle (to bring the roller closer to the shaft).

now i believe the valves are .341 and can only find .343 and .345 lash caps at summit, do i use the .343 caps? they pretty much are all .080 thick (do have the rocker shaft shims to play with it a little).

dont know really is that the size of my valves.
