Valve cover breathers / PCV advice

Greetings all,

I recently imported 6566 to the UK and have got it fully road legal here in the UK but have an issue.

The current set up on my Engine is with a Holley 770 Street Avenger with an Oval billet air filter assembly. The right side valve cover breather feeds the base of the cleaner and the left side breather / PCV goes to the manifold. That would seem OK.. but during a strip down / clean up, I noticed the air filter is not actually bolted down to the carb… On closer inspection, I can see why - you cannot attach the lower nut to the bolt of the assembly as the newly fitted MSD 8350 distributor fouls the access totally. The original owner simply assembled the cleaner / element and then friction fitted it to the carb.

So the point is that I am going to invest in a new Holley 64280 dog bone filter, but now wonder what the best way forward is regarding valve cover breathers / PCV (i.e. no PCV and have two plug in type breathers and cap off the manifold vacuum take off)?

Has anyone fitted a dog bone and solved the problem? Hopefully this may also solve some very minor smoke issues from the left bank when cold or on the over run!

Thanks in advance

Adrian
