GM Fast Burn Heads
Has anyone used CompCams dual valve springs or any other manuf. dual springs in these heads? I need a dual spring that will fit a 1.379" seat. I know GM has a dual spring because that is what I am using currently and I managed to break one 
, which is why I want to upgrade. Thanks,
Neil
