Default Re: Are oversized valves really needed?

Jim Kroeger ;

About 25% of the folks in our club have the touring set up as you describe, me included .The other 75% have stock engines and no over drive . When we all go on a tour we run max 45 mph . to keep the stock members happy . Note all these modification will improve performance with one requirement,higher RPMS for an engine designed to be a low RPM engine .
