Removal of emmision control piping from engine.

I have just rebuilt my carburettors and was told to get rid of as many of the rubber emmision control pipis of which there are many. I removed the charcoal container and piping.I am not sure where to run the pipes that connect to the valve covers.They used to go to the intake manifold.I will keep the flame arresters and probably run the lines down to a lower level.
Is this ok to do.Also i am not sure where a rubber line tjat joins the 2 carbs and tees in the middle.It ran somewhere can i just blank it of?
Took a million pictures but you never seem to take the one you need.
 
Is this for a V8 or four cylinder P6?

On the four cylinder TC you can remove most but keep the crank case breathers to to the carbs. Of you delete those you’ll lose the negative crank case pressure gone causing leaks and a change in mixture.
 
Removed the "emission control pipes" after cleaning out our 2000 TC carbs which were clogged with resin/gritty 'crud' from these pipes, connectors and the carb body. Blanked off all the carb connections. I feel confident this has made achieving a balanced tune between the carbs easier, perhaps by reducing the variables involved. Also, given the history of these fittings, I don't feel I'm adding any significant pollutants to the planet, given the total lifecycle savings of using the car instead of buying new ! :oops:
I retained the crank case breather, with the exit pipe now sending gasses through a filter and capture globe, and a motorcycle-style venturi exit to draw a vacuum through the filter as we move, so drawing gasses out of the crankcase and avoiding pumping them straight back into the carb/engine. I get around 2-3 mm2 per 1000km of hard driving, so if this volume changes I'll treat it as a prior warning of problems with my piston rings, etc. I'm sacrificing the negative crank case pressure at idle, but leaks from the the crankcase gaskets aren't a problem at this moment.
