The sheet on the exhaust says 160 seated and 380 at .620 lift. Coild bind at .775 lift. So they must be the comp springs. Not sure why they're worded differently. Seems the .025" installed height gives a decent amount more load. My curiosity is: Shouldn't the heavier intakes need a bit more than the exhaust if you wanted them different? Or is there a reason to have more spring on exhaust? You got it. I edited my last post, I don't think you saw it. Ok. Not sure if it was a typo or I don't quite get it lol. You said a race car would be 1.88-1.90 and the same for a street car. Should I make them all 1.9 or intakes 1.88 and exhaust 1.9?
