Upgrading cams or blower?
You need these!
These 125# Manley springs are new, yes they were installed on my TFS heads but never saw any actual usage. They were tested and indeed 120# seat pressure. They were removed as I went another route.
I will have them ready for shipment end of week.
Here's a link to product info, you'll find my price is fair.
