Also the differences in the springs go from 1.55 Dia. and say good for .680 lift and the 1.56 dia springs say good for .700 lift. and the tech said that was for solid roller cams.


0.660 lift with 1.50 is 0.704 with 1.60 and 0.748 with 1.70. Should've paid attention on math class the day when they did ratios and proportions!


Im not going to lie I am no math wiz! I do really appreciate the help. Thank you
I wonder if I could put these heads on right otb if they would work with my cam and 1.6 rockers.
