So I've got the 84cc big block heads, part# 60929 assembled for a flat tappet cam. I need to replace the springs to accommodate a roller and basically make them into part #60925. The only difference I can find between both of these assembled heads are the springs. They appear to both use the same locks and retainers. I'm working off of this PDF: https://edelbrock-instructions-v1.s3.amazonaws.com/edelbrock/60929.pdf

I've tried contacting Edelbrock Tech since last week, but was met with an automated message stating they were closed until today. Got greeted with the same message this afternoon, so who the hell knows when they're open. I can only assume it's the CA lockdown. Summit only has two sets of the roller springs left.


Is it as simple as ordering the springs and swapping them out?

Thanks again Moparts.
