I had a PVC valve stuck in the left stock valve cover, and just a pipe from the right cover going to the air cleaner. All stock. After 2000 miles, this is the result.
New 383 setup has no PVC or pipe: just breathers stuck in the covers.
Queston; should I knock out holes on the bottom of the lowered air cleaner and put stock plumbing back in? Exempt from smog checks, but just concerned about performance.
