The Right Valve Covers

Thanks for the responses.

I'm certain that I want to maintain the crank ventilation system; I'm not interested in any solution that discards it.

I also don't want to buy covers that might not work. I need to know that they'll clear.

The stock height is about 3.25" (to the raised breather port) and I have over 3/8" of gaskets underneath it.

I checked under the covers, and it seems that the baffles are what is taking the beating, even after beating them in.

Perhaps a baffleless cover would work? What is the disadvantage of not having them?

Does anyone know if either of the covers I listed will accept a crankcase ventilation system? I know the pictures show only 2 ports, but I also know that generic pictures get used a lot.
