your cam will definitely love bigger valves at the same compression.
maybe- maybe not
many times i Have got a flat spot just going to bigger valves and especially with a bigger cam at the same time
gotta keep the velocity up
maybe? yes it will. that grind is an updated street hemi grind purple shaft. the original was designed to be used with stock valve train in 340 motors without worrying about pushing a pushrod through a stamped steel rocker arm.
velocity tuning is what you do when you are class racing with mandated crappy heads. you have been reading too much chivvey straight 6 magazines.
