Head bolt holes need something

I just put a new spike breather and the two holes on both head have nothing in them. The threaded hiles are on the inside of each jug at the top that was used to bolt the factory breather mounting bracket. Does anyone know the thread size? Or does anyone know of something to put in them that looks cool? a spike or something?

thanks brothers:cheers:

Whwn you buy the spiked air cleaners for $400 there is a support bracket for another $200 that they don't tell you that you need.
Crazy!

Yep put on a support bracket (which is more bling) or you will be replacing alot of intake seals
 
Nelson can get everything you need, he had the best price and ordered it for me. Got the correct part and quick shipping. Just PM WB Cycles.
 
It is a hide away mount

The mount is a hide away made by S&S . It adjustable that mounts to the back of the carb and bolts to the bottom of the motor casing
