Signal73, Thats and idea. Seems like alot of work
For me if I had the older stud kit I think 12V FORD has a good idea. or you can grind the valve cover.
But with the newer stud kit it looks like milling the towers is the best way.
Yeah tom your not kiddin. I had my buddy mill my rockers down on his bridgeport miller. not a bad job at all and the studs have plenty of clearance with the valve covers.
