I Need Valvetrain Advice. I need help setting up my valvetrain on my LSX 427 with Texas Speed LS7 heads. The heads have the Ti intake valves and stainless exhaust valves and my cam specs are: 232/244 @.050 and .648/.648.
I am having trouble deciding on what valvesprings to run since I may end up running a cam with .700 lift down the road. Also, the stainless exhaust valve is heavier than the stock sodium filled exhaust valves and i may run into valve float issues if i don't have enough spring pressure.
So what do I do? Ditch the stainless valves and get the sodium filled? or do I buy some outrageously priced springs that will work?
