Not if you explicitly specify "custom version", i.e if you do:
Kernel Headers (Manually specified Linux version) --->
(4.1) linux version
Then you get:
BR2_KERNEL_HEADERS_VERSION=y
BR2_DEFAULT_KERNEL_VERSION="4.1"
which is what we want.

Yes for kernel version.

But no for kernel headers: see above what you should do.
Again, please look at qemu_*_defconfig, they do the right thing:
# Lock to 4.1 headers to avoid breaking with newer kernels
BR2_KERNEL_HEADERS_VERSION=y
BR2_DEFAULT_KERNEL_VERSION="4.1"
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_4_1=y
# Kernel
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_CUSTOM_VERSION=y
BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="4.1"
BR2_LINUX_KERNEL_DEFCONFIG="vexpress"
Best regards,
Thomas
