which retainers / seat cup
I'm having problems finding the right retainers and seat cups togo with my pac 1218 springs on stock lt1 heads. I keep hearing the stock retainers etc. Fit but they dont fit flush.
Anyone know which part numbers I need from experience?
Thanks

The Pac 1218 is a beehive spring, you can't use the stock retainer. You should be able to use the stock seat and locks with the comp 787-16. Most use the 648 lock.
