The last set of heads using these springs I did for a customer in Finland per John D said for the DC60 I set at 35.5mm this is good for lift up to 13.8mm . Should be 97 lbs at 35.5 closed pressure. He wanted them set closer to coil bind, the info from Eibach says 36mm Nice springs, you using stock retainers?

Ti retainers from Don @ EBS... Thanks Craig!

Two more things to watch out for, you will want to shorten the top of the valve guide by about .040 with that cam or the retainer might push into the valve seal. The Ti retainers, depending on what you have and using them with stock spring seats, with the Asco retainer I could not get any more installed height than 34mm we did not want to modify the head so opted to machine the spring seat cup.
