I have eddy performer RPM heads for BB. They have dual springs 1.550 OD from Edelbrock ,. Can I run my new Lunati dual springs which are 1.450 OD on these heads? Thanks for any help

Click to expand...

Perhaps you should ask your question to someone at Lunati for installed spring package dimd or Edlebrock (aka "Eddy") As they will be able to give you specific info re guide dimensions (aka "dims") like OD and height valve seat area, spot facing . Just a thought....

You could run that spring as it is smaller than the original spring diameter.
You would need to use the correct retainers, shims and spring locators for the new spring.

Gee, a 1.45 OD spring is really small. Not sure what they for but... As far as I know the EDE RPM's came with single springs, not sure what you have.
