I had a question concerning the FMS roller rockers. I have an E303 cam and want to go with the 1.7 roller rockers. Do I have to worry about valve clearance even though the pistons are notched already? Also I keep hearing that the intake needs a 1" spacer when used with the FMS 3 3/4 tall valve covers. When doing this will the hood clear the intake?

etc....

See post "Dished pistons required for E303 cam" The answer is yes you can use 1.7 ratio rockers for a E303 cam. For the second part of your question im not totally sure but I think you do need the spacer for the tall valve covers and a different hood for clearance issues. Frank..
