I beleive that a partially clogged fuel filter cost me a head gasket.
About a month ago I took out a head gasket when the car leaned out at the track. Changed the gasket, went to the track put in 116 made a pass and the O2's were 757! (Thank goodness for the race gas.) I had to bump FP to 48# to run 20# of boost. Changed my fuel filter - which was only 2 years old - went to the track 22# of boost, 45# FP and O2's were 808.
I think if you drain and refill your tank using jugs a lot, you need to change the fuel filter often. I know I will replace mine every Spring. Filters are much cheaper than doing head gaskets.
