I'm running a 351w with performer RPM intake and a spacer under my quickfuel 750. I want to go with the oval cleaner and cobra valve covers. I have read some info about valve cover clearance with some of the covers. Anyone have a part number listing that I should be looking for. I have also seen different sizes with regards to the air cleaner assemblies. I'm looking for some real world advice here and need to act fairly quickly. I'm about a solid weekends worth of work away from being ready for paint. I'd like to pop the filter on and check clearance before sending it off.

Thanks
