I am getting ready to install a Lt1 cam, holley 300-66 intake and either my holley 502-9 or 454 TBI unit. I am going to keep the swirl 193's for now and just install new springs and seals. I am unsure of the spring size and especially the seal size I need without machining. I am not removing the heads. I found this kit that I need confirmation on https://www.summitracing.com/parts/sum-174000/overview/ . If anyone could help me out or let me know the size spring/seals I would appreciate it.
