I have a Roush 427R that I'm wanting to replace the stock valve covers with the finned 427 Cobra Ford Racing VCs. They all have a caveat that they may need modification to work with roller rockers. I did a search but couldn't locate a thread dealing specifically with the 427R and replacement VCs
Anyone have experience with this engine and aftermarket VCs as far as clearing the rockers?
