An intake valve .100"" longer will not work well in an SCJ head. The valve tip gets to close to the intake stud for rocker arm fitment. I have done it but, using a Small Block Ford intake rocker arm.

You should be able it pickup .050 with some retainers and .050 with proper locks.
You need proper springs to install at 1.95 or 2.0

Get a cam with ~.700" lift and use the SCJB springs.

You will need a plus retainer also, if you just have to have that much lift.
