It will decrease valve to piston clearance on either the intake or the ex valves (not sure which). will make it more likely to ping at lower RPM's. Will want a timing change (if you want it spot on). All (except VP clearance) stemming from the change (increase) in cyl psi. Need more info on the build. live every 24 hour block of time like it's your last day on earth
