Hi, I just purchased a set used PRC dual spring kit that has 3100 miles on them. I am planning on putting this set on to a set of brand new 243 heads and HPE 224/224,580/580,114 cam and was wondering upon install can i just use the stock 243 head's stock spring seats & seals with the springs since they are brand new or do i have to use the used one's from the PRC seats& seals? Also, do i use any shims for the spring seats? And do i have to do any machining where the spring will seat,since these are duals? Sorry guys I'm a newbie at this. PLease help with any info,really appreciated

Use the seats that came/go with the PRC duals, as well as their retainers. No machining. Shims should not be necessary.

Not sure on the seals.
