questions regarding the Map ultimate duty valve springs
Hi guys, I have a set of your ultimate duty valve springs, and I (actually my machinist) have some questions. What should the installed height be? What is the rate? Can they be used with stock spring seats? Is it ok to use stock retainers? I'm running a stroker, so ill only see 8k rpm.
Thanks in advance.
