i need some advise on whats best on a modified ls7 engine i want to upgrade my valves with either tit or ss valves what you guys think will work best ?
it is a big valve, GM does not use the titanium valves because they are cheap. they use them because when you spin a 2.25 valve up that high, and do not want to use a monster spring, you need a light valve to keep things moving and not bouncing.. if for some reason you feel the need to replace the factory valves, they need to be titanium

ok so if im not going over 8000 rpm do you think titanium are needed? i heard that ferras make a light weight ss valve the work great below 8000rpm.
