valves vs spring pressures???
valves vs spring pressures??? running 140/385 pressures on a stock valve thats had a 5 angle valve job.
the machine shop says the stock valves are too thin to handle the pressures my cam requires..... but everyone and their grandma runs similar setups with stock valves and have had good sucess with them.
ive run the same valves without a valve job for 2 years now on these spring pressures with no issues. street/track driving. im pretty abusive.
any opinions?
