Gen 2 valve spring question

[ncyellowbusa]

Wanting to put a n2o system and a few other odds and ends on my '13le. Was wondering if its possible to change the valve springs with the motor still in the frame and what type of spring compressor I need to look for if its possible. I've got a air operated spring compressor but will have to pull the head to use it and didn't want to do that until I pulled it down for cams and port work.
Are most guys running the 47 or 65 springs with stock cams?

With the Ti valves there is only 1 or 2 springs you can use, and they are around 47lbs. As for installing them, like some cars, i dont think it can be done.

Don't know anything about anything, but if I was gonna work the motor, I would do everything at one time. Best of luck.
