I’m about to start checking the valve to valve clearance after fitting a pair of Newman ph4 cams 

dose anyone know what the “safe” tolerance would be for these?

do you have uprated valve springs and aftermarket pistons?

Yes

just realised you said valve to valve, if they're timed correctly  that should not be a concern.

Sandy brown is going to map the car and has asked what the valve to valve clearance is 

I assume he needs to know when adjusting timing that there is no chance of v2v contact
