Is it more common to break an intake valve spring verse the exhaust valve spring? This is the second time I have broken an exhaust valve spring and both mechanics thought it was strange that it was the exhaust spring that broke.

Not sure which break more often: Exhaust or Intake Valve Springs. Which springs are you breaking. Are they the stock springs or an aftermarket valve spring? The reason I ask is if you are making 375 rwhp and you think you have a stock cam, I'm betting there is an aftermarket cam in your car (assuming you bought the car used and don't know for sure). You may want to put a dial indicator on the rocker and measure the lift, stock should give you around .5" times 1.7 rocker arm ratio for a total of .85 inches. If you are running stock springs with an aftermarket cam you will start breaking them right and left.
