Ford racing valve covers

Post  NO FAIR on August 1st 2015, 1:36 am

Hi All,
Has anyone had clearance issue with there valve springs hitting the side of the covers? My number 5 exhaust valve spring is rubbing the inside where the indentation groove where it bolts to the head. Is it normal to have to clearance these valve covers? I think I just need to hog the holes out just a touch and push the valve cover down a little so it clears. Am I on the right track?
Thanks for any input.

P51 or SCJ heads?

If so, you'll need to grind the inside of both covers to get that spring to clear. Check clearance through a full rotation cycle of the spring. I had to take off more than I thought I would.

Most just need a slight barbering the inside of that bolt column and then twist the cover on installation, counterclockwise as much as you can with the bolts loosely installed.

A 1.630" O.D. spring needs more. Personally, I use a "beehive" spring on the exhaust side with a SCJ head whenever it warrants.

My P-51 heads with 1.65 valves rubbed. I had to "massage" them a bit and they work fine now.
