revhead347 Apparently my ex-husband made that mistake. 20+ Year Stangneter Jun 14, 2004 9,301 1,644 214 Acworth, GA May 24, 2014 #41 May 24, 2014 #41 I don't know specific numbers. My last engine had a lift of .595" on the exhaust and I drove it for 10 years and 85,000 miles and the springs never broke. I'm sure they were pretty worn out towards the end, but they never broke.
