im gonna have to inquire about the offset.I also know Chris Uratchko said good things a while back about comp part # 843 lifter being used on Butch Kemps motor spinning 9000+ he said over 100 passes and they looked perfect..they were also about 400 beans



I had a set in my 59* stuff for 6 or 7 years 1000s of passes never a problem. Still have them in a box nevered failed just switch to 48*.
