FR500 Cams swap question (now 4 sale on Ebay)

I was about to put FR500 cams, springs and retainers on stock heads without pulling the heads and changing valves (to FR500 valves). Can I do that ? Ford makes it sound as though you must user Fr500 valves with the FR500 cams ?

Help. Anyone ?

That's what I thought and could see the difference in the valves to. So that means, that one cannot swap in FR500 cams, springs, and rockers in without pulling the heads and changing valves.

Thanks for the info.
 
A complete valve job to the heads would definately be in order especially if youre going with a new set of valves....As for the stock springs, they are quaility pieces, and just as long as you limit the lift numbers to .465 you will be fine..the 4v benefits more from duration than lift...DA snake boy!!!
