Valve spring removal and PB Booster is in the way

I am in the process of tearing down my 340 for a Cam and other parts change and I’m looking at the Power Brake Booster and it looks like I will not be able to get to the 3 valve springs closest to the firewall because the Booster is in the way!
Is there any way to remove the valve springs with it there or do I need to unbolt it?
