Are there any advantages to using titanium valves in an engine that will only see 7000 max rpm? We are running VERY aggressive cam profiles with high rocker arm ratios now. Don't have a problem with valve train separation, but am searching for more gains, small as they may be.

THERE WOULD BE SOME GAINS WITH THE LIGHTER VALVE BY REDUCING THE SPRING PRESSURE.YOU CAN ALSO SLEEVE YOUR GUIDES AND GO WITH A 7MM INT VALVE STEM THIS WILL PICK UP SOME FLOW AS WELL AS REDUCE WEIGHT.IF YOU DONT HAVE A COMPRESSION RULE THE TITANIUM VALVES WITH THE THICKER HEADS WILL PICK UP SOME COMPRESSION AS WELL .THE ONLY DOWN SIDE IS THE COST.YOU CAN GET AROUND THAT WITH USED CUP VALVES THAT YOU CUT DOWN THEY WILL GO A SEASON AT LEAST
