I don't think you'll have a problem with those lifters . . . also, they're already broken in with the cam in the engine, so I'd use them. Make sure they go back in the same lifter bores.

Given that this is a street engine, you don't need much more than 50 lbs on the seat - as you're not going to rev the heck out of it anyway. The only way to know the installed spring height is to have a spring put on a spring tester (auto-machine shops have them) - and see what height gives you 50 lbs. There is no way to know what the correct installed height is without doing this step.
